0001 #ifndef __PID_H__ 0002 #define __PID_H__ 0003 0004 // 0005 // Hello PID Fans: 0006 // 0007 // This is the base class for a simple set of objects that 0008 // are used to evaluate various detector technology choices for the EIC. 0009 // 0010 // The idea is simple. Regardless of PID detector technology choice 0011 // one must be able to answer some simple questions. This virtual base class 0012 // organizes the method of asking and answering these simple questions to 0013 // allow for efficient and apples-to-apples comparisons. 0014 // 0015 // The base class requires that any derived class procide responses to several queries: 0016 // -- valid (double eta, double p ); 0017 // -- numSigma(double eta, double p, PID::type PID); 0018 // -- maxP (double eta, double numSigma, PID::type PID); 0019 // -- minP (double eta, double numSigma, PID::type PID); 0020 // -- name (); 0021 // 0022 // Here PID::type is an enumerated constant set allowing one to choose pi-vs-k or k-vs-p etc... 0023 // 0024 // The detector types that inherit from PID will clearly have parameters that define their 0025 // performance and these are expected to be arguments of the constructor of those derived classes. 0026 // For example: 0027 // PID* tof = new tofBarrel(radius, etaLow, etaHigh, sigmaT); 0028 // 0029 // 0030 0031 #include <string> 0032 0033 class PID 0034 { 0035 public: 0036 PID() {} 0037 virtual ~PID() {} 0038 0039 enum type {pi_k , k_p}; 0040 0041 virtual bool valid (double eta, double p )=0; 0042 virtual double numSigma (double eta, double p, PID::type PID)=0; 0043 virtual double maxP (double eta, double numSigma, PID::type PID)=0; 0044 virtual double minP (double eta, double numSigma, PID::type PID)=0; 0045 virtual std::string name()=0; 0046 virtual void description()=0; 0047 0048 protected: 0049 0050 }; 0051 0052 #endif /* __PID_H__ */
