0281     decrease of hadron's kinetic energy by ionization loss.</LI>

0282 <LI>Extended cross-sections for the computation of light anti-nuclei on hydrogen.

0283     Extended nuclear cross-sections also for light hypernuclei and anti-hypernuclei

0284     projectiles.</LI>

0299     mesons and baryons in proton-proton interactions, as measured by the

0300     NA61/SHINE Collaboration.

0301     Also improved description of leading particle spectra in meson-nucleon

0302     interactions.</LI>

0303 <LI>Revised the mixing probability between vector mesons (<TT>rho0</TT> and

0304     <TT>omega</TT>), as well as the probabilities for the ratios between

0305     pseudo-scalar and vector meson production for both FTF and QGS string

0306     fragmentations, to improve the description of NA61/SHINE experimental

0307     data.</LI>

0308 <LI>New singleton class G4FTFTunings to allow to specify alternative sets

0309     of FTF parameters, called "tunes"; added also specific UI messenger.

0310     Currently, the feature is mostly meant for use in internal tests,

0311     further study and development; in the future, such tunes may be offered

0312     to users for specific studies.</LI>

0313 <LI>Added option to G4HadronicParameters to control the diffraction

0314     dissociation for nucleon projectile on target nucleus with baryon number

0315     greater than 10: by default, both projectile and target diffraction are

0316     switched off (but they are both active in the case of target nucleus with

0317     baryon number below or equal to 10; if instead the flag is set to "true",

0318     then both projectile and target diffraction are activated regardless of

0319     the target nucleus).</LI>

0346     transport of light hypernuclei and anti-hypernuclei, switched off by

0347     default. When enabled, the following interactions are included:

0348     a simplified treatment of weak decay; ionization and multiple scattering

0349     for the charged particles; nuclear elastic scattering; nuclear inelastic

0350     scattering, handled by either the FTF string model or by the INCL

0351     intranuclear cascade model, with a very simplified treatment of nuclear

0352     de-excitation.</LI>

0353 <LI>In G4RadioactiveDecayPhysics time limit for radioactive decay is now

0354     coherent with the limit used in the nuclear de-excitation. The default

0355     limit of <TT>1 ns</TT> may be changed via UI command.</LI>

0356 <LI>All DNA physics lists are now combined with standard EM models. The

0357     default upper energy limit of <TT>300 MeV</TT> may be increased or

0358     decreased. DNA physics may now work with radioactive decay.</LI>

0401 <UL>

0402 <LI> A potential CPU time increase could be experienced due to the new maximum

0403      value for relative accuracy of integration of charged particle tracks in

0404      field (<TT>epsilon_max</TT>). This can be due to extra steps for low

0405      energy electrons or muons moving in (near) vaccuum.

0406      Potential remedies: either use (the more efficient) templated equation

0428 <LI>FTFP_BERT pion showers have slightly (~0.5%) higher energy response and

0429     (~2%) narrower lateral shapes with respect to release 11.0.3. QGSP_BERT

0430     pion showers have slightly (~0.5%) lower energy response and (~2%) wider

0431     lateral shapes. Comparing QGSP_BERT pion showers with those of FTFP_BERT,

0432     they become closer to each other with respect previous versions, with

0433     the QGSP_BERT pion showers still having slightly higher energy response,

0434     significantly wider energy resolution, and longer and narrower shower

0435     shapes with respect to those of FTFP_BERT.</LI>

0591 <H3><I>Analysis</I></H3></A>

0592 <UL>

0593 <LI>Implemented support for writing analysis objects (histograms, profiles,

0594     n-tuples) in a file multiple times: with Root output type, the object

0595     cycle number is attributed automatically; with other output types that

0596     do not support object cycles, the object name is appended with

0597     <TT>_vN</TT>, where <TT>N</TT> is the number of the write cycle, when

0598     the object is written more than once; no extension is added when the

0599     object is written for the first time (cycle 0).</LI>

0600 <LI>Added new UI commands for analysis file management, supporting also multiple

0601     write with/without calling write and/or reset in between two runs:

0602     <TT>/analysis/openFile, write, closeFile</TT> and <TT>reset</TT>

0603     <TT>/analysis/setDefaultFileType</TT>.</LI>

0604 <LI>Implemented new analysis manager List functions and associated commands:

0605     <TT>/analysis/list [onlyIfActive]</TT>,

0606     <TT>/analysis/xy/list  [onlyIfActive]</TT> where

0607     <TT>xy = h1, h2, h3, p1, p2, ntuple</TT>.</LI>

0608 <LI>Added UI commands for visualization: <TT>/analysis/hn|pn/getVector</TT>.</LI>

0609 <LI><U>Internal changes</U>:

0610     <UL>

0611     <LI>Replaced G4TNtupleDescription, G4RootPNtupleDescription structures with

0612         classes more suitable for adding members for handling n-tuple cycles.</LI>

0613     <LI>Changed namespace for g4tools code from <TT>tools</TT> to <TT>toolx</TT>

0614         for externals.</LI>

0615     <LI>Added G4RootRFile type = a tuple for the Root read file including its

0616         directories, analogue to G4RootRFile for Root output, used now in the

0617         G4RootRfileManager::fRFiles map instead of tools::rroot::file.

0618         This allows deleting file directories in the class destructor, and

0619         should fix a reported Coverity defect.</LI>

0620     <LI>Refactored analysis manager methods for file handling from the output

0621         specific managers in the common implementation in G4ToolsAnalysisManger.

0622         Besides code simplification, this guaranties identical behaviour with

0623         generic analysis manager.</LI>

0624     <LI>Introduced a common implementation for histogram/profiles manager.<BR>

0625         New classes:

0629         <LI>G4THnMessenger - replaces G4H*|P*Messenger class.</LI>

0630         <LI>G4HnDimension - helper type to manipulate ndim, xmin, xmake

0631             parameters.</LI>

0633         Updated classes:

0634         <UL>

0635         <LI>G4THnManager: added a vector of pairs of histogram and information

0636             as a data member to simplify the access when both objects are used.</LI>

0637         <LI>Updated HnInformation structures functions to use compacted

0639         <LI>Updated functions in G4AnalysisUtilities.</LI>

0640         <LI>In all messenger classes, replaced the usage of the analysis

0659     <LI>Fixes in deleting files: do not delete (not empty) main n-tuple files

0660         with generic analysis manager, delete empty n-tuple csv and xml files

0661         created on the main thread.

0662         Fix in deleting files (root): do not delete the final (merged) file

1406         Also fixing event non-reproducibility for the case when radioactive
1407         decay is enabled on top of any physics list.
1408         Simplified handling of floating levels. For floating levels check if

1412     <LI>G4ExcitationHandler: use IsLongLived() flag from G4Fragment to decide

1414         Introduced de-excitation of fragments with lambda inside. Added
1415         protections that prevents potential crashes and large energy
1416         non-conservations in  case of hypernuclei and anti-hypernuclei
1417         projectiles. Added extra sanity check for negative value of lambda
1418         inside a fragment.
1419         Note: there are still a few warnings of rejected candidate final-states
1420         with off-shell masses and few GeV energy non-conservations (implying a
1421         resampling of the final-state) in the case of light hypernuclei and

1449         Note: most of the considered light anti-hypernuclei projectiles have
1450         baryon number equal to -4 : it is assumed that their properties are similar
1451         to anti-He4, therefore their elastic scattering is set-up as for anti-He4
1452         elastic nuclear scattering. These properties can be improved in the future

1521         In methods AdjustNucleonsAlgorithm_beforeSampling() and
1522         ComputeNucleusProperties(), check if the residual is a single nucleon
1523         (or lambda) or a pair of nucleons (or lambdas); also use the absolute
1524         value of the nuclear residual charge to take into account the case of
1525         anti-nuclei projectiles.</LI>
1526     <LI>G4FTFAnnihilation: reorganization of Create2QuarkAntiQuarkStrings() and
1527         Create3QuarkAntiQuarkStrings() methods, in order to better handle
1528         unphysical configurations that need to be rejected.
1529         The algorithm has been also optimised by changing the order of the
1530         sampling: light-cone variables are sampled first, then transverse momenta.
1531         The positions of quark and anti-quark in strings have been corrected: this
1532         is expected to improve the kinematical properties of the produced
1533         hadrons.</LI>
1534     <LI>G4FTFTunings: new singleton class to allow the possibility to specify
1535         alternative sets of FTF parameters, called "tunes".
1536         Moved into this class some special, internal classes, useful for tuning
1537         of parameters, that were originally in G4FTFParameters.</LI>
1538     <LI>G4FTFTuningsMessenger: new messenger class for G4FTFTunings.</LI>
1539     <LI>Allow control of diffraction for baryon number greater than 10 in
1540         G4FPFParameters. The option comes from G4HadronicParameters and the
1541         default behaviour remains the same (i.e. off).
1542         Use of the new G4FTFTunings class; instead of having one, single set of
1543         parameters, it has now an array of set of parameters, with each element
1544         corresponding to one specific "tune".
1545         Clean-up of the class by moving to G4FTFTunings some code.</LI>
1546     <LI>G4HadronBuilder: added a new argument in constructor, and a new data
1547         member to the class. This is needed to set a special mixing of
1548         pseudo-scalar and vector mesons for s-sbar mesons. Introduced to
1549         describe phi-meson production in proton-proton interactions measured
1550         by NA61/SHINE.</LI>
1551     <LI>G4VLongitudinalStringDecay: tuned the probability of pseudo-scalar meson
1552         production, to describe K*0 meson production in proton-proton
1553         interactions according to NA61/SHINE data. Introduced also a new
1554         parameter (probability of pseudo-scalar meson production in s-sbar
1555         mesons) to increase the phi-meson yield in proton-proton interactions.
1556         Fixed a bug in mixing eta_prime and phi mesons in the quark systems
1557         d-dbar, u-ubar and s-sbar.
1558         Brought back the value (0.5) of the mixing between (rho0 and omega)
1559         vector mesons as it was originally before version 10.0. This should
1560         describe better NA61/SHINE experimental data. The change has some effect
1561         on the hadronic showers, giving that the various vector mesons have
1562         different decay rates into neutral pions.</LI>
1563     <LI>G4VPartonStringModel: added debugging information on the number of
1564         lambdas for residual projectile hypernuclei.</LI>
1565     <LI>G4HadronBuilder, G4VLongitudinalStringDecay, G4LundStringFragmentation,
1566         G4QGSMFragmentation, G4ExcitedStringDecay: in order to describe the
1567         NA61/SHINE data on K*0 and phi mesons production in proton-proton
1568         interactions, different probabilities were introduced for the ratios
1569         between pseudo-scalar and vector meson production. These ratios are the
1570         following: for ordinary mesons from u- and d- quarks, the ratio is 0.5/0.5;
1571         for strange mesons the ratio is 0.4/0.6; for mesons with hidden strangeness
1572         (as for phi), the ratio is 0.3/0.7.
1573         This approach is similar to the one adopted in Pythia8.
1574         It is also assumed that the probabilities for hidden strangeness (0.3/0.7)
1575         apply for mesons with hidden charm and beauty.</LI>
1576     <LI>G4LundStringFragmentation: introduced few changes for a special
1577         treatment of the last string decay in the case of <TT>ss-q</TT> or
1578         <TT>ss-qq, ss-sbar sbar</TT> last string decay. This improves the
1579         yield of <TT>anti-Xi</TT> hyperons in proton-proton interactions
1580         according to the NA61/SHINE data.<BR>
1581         Moreover, some parameters have been tuned to better describe the
1582         NA61/SHINE data on various particles produced in proton-proton
1583         interactions.</LI>
1584     <LI>G4DiffractiveExcitation: improved ExciteParticipants_doChargeExchange()
1585         method: for a projectile meson in the case of quark exchange, a more
1586         correct ratio between pseudo-scalar and vector mesons is included; the
1587         pion after the exchange can transform into <TT>pi0, eta, eta', rho0</TT>

1588         and omega mesons. This allows to improve the description of leading

1709     lifetimes in nuclear de-excitation code. In G4NuclideTable, changed

1710     <TT>threshold_of_halflife</TT> from <TT>1000 ns</TT> to <TT>1 ns</TT>.</LI>

1716     Default minimum mean life is <TT>1.0 ns</TT>.

1717     In <TT>/particle/nuclideTable/min_halflife</TT> changed default minimum

1718     half-life to <TT>0.693 ns</TT>.</LI>

1719 <LI>Changed half-life threshold for nuclide creation to be consistent with

1720     lifetimes in nuclear de-excitation code; in G4NuclideTable constructor,

1723 <LI>Use nuclide mean-life instead of half-life in G4NuclideTable in order

1725     two new methods, SetMeanLifeThreshold() and GetMeanLifeThreshold() so

1726     that the life-times can be accessed as either half-life or mean-life.</LI>

1727 <LI>G4Triton, G4AntiTriton: corrected the lifetime value for triton and

1728     anti_triton: the half-life (12.32 years) was incorrectly used instead of

1729     the mean lifetime (17.774 years) for triton, whereas the anti_triton was

1730     incorrectly treated as stable.</LI>

1957         twinkling in UI commands in G4VisCommandsTouchable and

1958         G4VisCommandsViewer.</LI>

1959     <LI>Implemented generic cutaway. Prior to this, cutaways were implemented

1960         only in OpenGL by using OpenGL's clipping plane feature. This still
1961         pertains for OpenGL since it is very fast, but here cutaways are
1962         implemented using Boolean operations in a reasonably robust and
1963         reliable way. Based on the initial motivation and implementation on
1964         the management side from
1965         <A HREF="https://github.com/Geant4/geant4/pull/53">GitHub PR#53</A>.</LI>
1966     <LI>Re-worked and rationalised special mesh rendering utilities.
1967         The idea is that these are "standard" functions that are optional.
1968         They are optimised for OpenGL but they also work fine for ToolsSG and
1969         Qt3D. An attempt to draw a mesh with any other driver will result in a
1970         warning and only the container will be drawn. Other drivers will have to
1971         implement their own AddCompound(...G4Mesh...) function or choose to use
1972         the standard functions or some thereof.</LI>
1973     <LI>Take advantage of recent developments in HepPolyhedron for rendering:
1974         conversion of tetrahedra to enclosing polyhedron removing inner surfaces;
1975         conversion of boxes to enclosing polyhedron removing inner surfaces.
1976         Also take advantage of developments in G4PhysicalVolumeModel:
1977         when a mesh has been found, an artificial node is created and added
1978         to the PVPath whose physical volume points to the parameterisation.</LI>
1979     <LI>G4VisCommandsViewer: <TT>/vis/viewer/centreOn</TT> and
1980         <TT>centreAndZoomInOn</TT>:
1981         only fly and twinkle if 'KernelVisitElapsedTimeSeconds < 0.1'.
1982         Introducing <TT>/vis/viewer/resetCameraParameters</TT> UI command, resetting
1983         *only* the camera parameters (view direction, etc.).</LI>
1984     <LI>G4VSceneHandler: added utility function Draw3DRectMeshAsDots(..); for a
1985         rectangular 3-D mesh, draw as coloured dots, one dot randomly placed in
1986         each visible cell. Tidy Draw3DRectMeshAsDots().
1987         Allow for multiple meshes in a single screen; relevant for special mesh
1988         rendering.
1989         Implemented GetPointInBox() and GetPointInTet() to sample a random point
1990         inside a box and a tetrahedron.
1991         Exploit move operator when creating polyhedra for Special Mesh Rendering.
1992         Numerous improvements to comments and messaging.</LI>
1993     <LI>Introducing drawing of parameterised tetrahedral mesh.

2000     <LI>G4VisCommandsTouchable: augment <TT>/vis/touchable/draw</TT>, added Boolean
2001         argument: if true, draw the extent (bounding box); Default false.
2002         In <TT>/vis/touchable/dump</TT>, fix missing dump of vis attributes.</LI>
2003     <LI>G4VViewer: added data member and access method for
2004         <TT>KernelVisitElapsedTimeSeconds</TT>. This is measured in
2005         ProcessView().</LI>
2006     <LI>In G4VisExecutive, introducing 'FALLBACK' drivers for TSGQt and VTKQt.
2007         A FALLBACK vis driver is selected if the user chooses a UI session that
2008         is not compatible with the requested driver. For example, if the user
2009         has built Geant4 with Qt, the TSGQt driver will be available and be
2010         the "default" driver, so <TT>/vis/open TSG</TT> will attempt to open
2011         TSGQt. But if the user has chosen a dumb terminal session, the vis
2012         manager selects TSGX11, for example, instead. Added TOOLSSG_OFFSCREEN.</LI>
2013     <LI>Improved messaging for the case that a driver is not found in the
2014         candidate list.</LI>
2015     <LI>Changed G4cout to G4warn in those cases where 'verbosity >= warnings'.</LI>
2016     <LI>Introduced compound command: <TT>/vis/plot <h1|h2> <id></TT>.
2017         This is the first part of a programme to facilitate the drawing of
2018         plots (if any have been registered with the analysis manager) at the
2019         end of a run. At the moment only the ToolsSG vis driver can offer this,
2020         so the vis manager issues appropriate messages.
2021         Later, we hope to introduce something like <TT>/vis/reviewPlots</TT>,
2022         which will allow the user to view all available plots in sequence.</LI>
2023     <LI>G4VisManager: added access method: IsEnabled(). Register the new
2024         commands. In EndOfEvent(), protect view checking with mutex lock
2025         in MT mode, and deal better with the case of scene requesting no kept
2026         events (greatly speeds plotting).
2027         Only print list of available histograms if more than one per category.
2028         GeometryHasChanged() is a method that is called by the run
2029         manager. Sometimes the user chooses to delete the existing geometry
2030         tree and ask the run manager to construct a new detector geometry.
2031         Previously existing vis models of the geometry become invalid and the
2032         vis manager had to pick up the new geometry.
2033         The vis manager removes invalid models from the vis scenes and now adds
2034         the new version of the world back in. Other types of models, trajectory
2035         drawing, for example, if specified in the original scene, are kept in
2036         the new version of the scene.<BR>
2037         Implemented G4VisManager::DrawGeometry(), drawing a geometry tree starting
2038         at the specified physical volume.</LI>
2039     <LI>G4VisCommandsSceneAdd: new command <TT>/vis/scene/add/plotter</TT>,
2040         to add G4PlotterModel to end-of-run list.
2041         Adapted <TT>/vis/scene/add/volume</TT> UI command to new
2042         G4PhysicalVolumesSearchScene.</LI>
2043     <LI>G4Scene: redefined IsEmpty().</LI>
2044     <LI>G4VisCommandsViewerSet: improved messaging for
2045         <TT>/vis/viewer/set/lineWidth</TT>; this simply prints a message saying
2046         how *actually* to change line width.</LI>
2047     <LI>Introducing <TT>/vis/viewer/set/specialMeshRenderingOption <dots|surfaces></TT>
2048         UI command; "dots" draw one dot per mesh point; "surfaces" group mesh
2049         points by colour and material and compute the outer surface or envelope,
2050         removing internal shared faces. So far, only the "dots" option is
2051         implemented for some drivers.</LI>
2052     <LI>Introducing <TT>/vis/viewer/set/lineWidth</TT> UI command, a do-nothing command
2053         that tells how to change line width.</LI>
2054     <LI>Implemented </TT>/vis/reviewPlots</TT> UI command.</LI>
2055     <LI>G4VisCommandsSceneAdd: changed the default width of axes added to the
2056         scene with automatic length and width determination.</LI>
2057     <LI>G4VisCommandsCompound, G4VisCommandsSceneAdd, G4VisCommandsTouchable,

2060 <LI><B>Modeling</B>
2061     <UL>
2062     <LI>G4Mesh: augmented available data for 3D rectangular mesh.
2063         Programmed for parameterised tetrahedron mesh.
2064         Simplified algorithm: now finding 1-deep rectangular meshes such as
2065         G4PhantomParameterisation.
2066         A simple parameterisation may only be one level; nested
2067         parameterisations may be 2- or 3-level.</LI>
2068     <LI>G4PhysicalVolumeModel: added <TT>LocalExtent</TT> and <TT>GlobalExtent</TT>
2069         to method GetAttDefs().
2070         Added modifiers; for AddCompound(mesh), provide an artificial node as
2071         an (optional) hook for anything that might be generated.
2072         Implemented generic cutaway: in G4PhysicalVolumeModel::DescribeSolid(),
2073         simplified clipping, sectioning and cutaway code.</LI>
2074     <LI>Migrated G4PhysicalVolumesSearchScene and G4TouchablePropertiesScene

2076     <LI>Retired G4BoundingSphereScene and G4PhysicalVolumeSearchScene.
2077         G4BoundingSphereScene accumulated bounding spheres and often
2078         overestimated the extent of the scene; it is now superseded by
2079         G4BoundingExtentScene. G4BoundingExtentScene deals directly with
2080         extents, which makes it neater and more tightly estimates the overall
2081         extent of the scene.</LI>
2082     <LI>G4PhysicalVolumeSearchScene is superseded by
2083         G4PhysicalVolumesSearchScene. G4PhysicalVolumesSearchScene finds all
2084         occurrences of a physical volume and returns a "findings vector".
2085         Removed last ambiguous and misleading argument in the constructor.</LI>
2086     <LI>G4PseudoScene: added AddCompound(const G4Mesh&) method; if special mesh
2087         rendering is set, this catches mesh candidates (certain types of
2088         parameterisations) and avoids descending into the parameterisations.</LI>
2089     <LI>G4PhysicalVolumeModel: added SetSpecialMeshRendering(true) to avoid
2090         traversing (certain types of) parameterisations (see above).
2091         Eliminated <TT>goto</TT> statements.</LI>
2092     <LI>Allow arrow proportions to be greater than 1/100. Produces more visible

2171         Currently, the ToolsSG viewer cannot draw trajectories in MT mode, so
2172         in function SwitchToMasterThread() we draw any events that have been

2726 <H3>A1 - Location of Geant4's datasets<I></I></H3></A>
2727 <P> </P>
2728 Use of environment variables to locate Geant4's datasets at application

2729 runtime is now optional, the following fallback-based search is being used

2730 for backward compatibility with existing setups:

2731 <UL>

2732 <LI>If an environment variable for an individual dataset, e.g.

2733     G4ENSDFSTATEDATA, is set, then this is used as the location of that

2734     dataset and no further search for that dataset is performed.

2735     The toolkit code raises a <TT>G4Exception</TT> if the dataset is not

2736     present.</LI>

2737 <LI>If the GEANT4_DATA_DIR environment variable is set, then this is taken

2738     as a directory under which all datasets are located, and no further

2739     search is performed. The toolkit code raises a <TT>G4Exception</TT> if

2740     the requested dataset is not present in this directory.</LI>

2741 <LI>If none of the above environment variables are set then datasets are

2742     searched for under the following ordered sequence of paths:

2743     <OL>

2744     <LI>The (absolute) path set at configuration time by the

2745         GEANT4_INSTALL_DATADIR CMake variable;

2746     <LI>Subdirectories <TT>share/Geant4/data</TT>, <TT>share/geant4/data</TT>,

2747         <TT>share/data</TT>, and <TT>data</TT> of the Geant4's install
2748         location as set at configuration time by the CMAKE_INSTALL_PREFIX
2749         CMake variable (<TT>C:\\Program Files</TT> (Windows only);
2750         <TT>C:\\Geant4</TT> (Windows only); <TT>/usr/local</TT>,
2751         <TT>/usr</TT>).
2752     </OL>
2753     The toolkit code raises a <TT>G4Exception</TT> if the requested dataset
2754     is not found in any of these locations.</LI>
2755 <LI>User code that directly accesses the datasets should migrate from use
2756     of raw <TT>std::getenv()</TT> calls to the builtin <TT>G4FindDataDir</TT>
2757     free function, e.g.
2758     <PRE>
2759     #include "G4EnvironmentUtils.hh"
2760
2761     // const char* p = std::getenv("G4ENSDFSTATEDATA");
2762     const char* p = G4FindDataDir("G4ENSDFSTATEDATA");
2763     </PRE>
2764     which implements the above search sequence and does not rely on the
2765     per-dataset environment variables being set; <TT>nullptr</TT> is
2766     returned if the dataset is not located, it being up to the callee to
2767     decide what to do in this situation.</LI>
