0011 This example demonstrate 4 ways of the usage of G4ParticleGun shooting
0012 primary particles in different cases.

0016
0017 This example demonstrates the usage of G4GeneralParticleSource for generating
0018 primary incident particle according to user defined distributions.

0023 This example shows how to create a primary event including several vertices and
0024 several primary particles per vertex.
0025
0026 HepMC
0027 ------
0028
0029 This directory contains examples for using HepMC as an interface with
0030 various Monte Carlo event generators, such as PYTHIA.
0031 It also include an example for demonstrating MC truth handling with HepMC.
0032
0033 pythia
0034 ------
0035
0036 This directory contains the following examples:
0037
0038 a) use of Pythia6 as Monte Carlo event generator, interfaced with Geant4,
0039 and showing how to implement an external decayer based on Pythia6.
0040 The feature is activated by setting environment variable PYTHIA6 to point
0041 to the Pythia6 installation area.
0042 For details, please see pythia/decayer6/README.
0043
0044 b) use of Pythia8 as an external decayer to replace native Geant4 decay
0045 tables for such resonances as tau+/- and B+/-, and to supplement Pythia8-based
0046 decay tables to those resonances where Geant4 native decay features are not
0047 implemented.
0048 For details, please see pythia/py8decayer/README.
