The (fake) Dalitz particle, which 00019 * is really just a pi0 with its Dalitz decay branch at 100%. It is added 00020 * so the embedding team can access it by the geant ID defined in gstar_part.g. 00021 * The hypertriton is also added. 00022 * 00023 * In both cases we define a fake PDG id in the header file StarPDGEncoding.hh. 00024 * 00025 * Revision 1.1 1999/05/14 18:50:04 ullrich 00026 * Initial Revision 00027 * 00028 **************************************************************************/ 00029 #ifndef StDalitz_hh 00030 #define StDalitz_hh 00031 00032 #include "StMeson.hh" 00033 00034 class StDalitz : public StMeson { 00035 public: 00036 static StDalitz* instance() {return &mDalitz;} 00037 static StDalitz* dalitz() {return &mDalitz;} 00038 00039 private: 00040 static StDalitz mDalitz; 00041 00042 StDalitz(const string & aName, 00043 double mass, 00044 double width, 00045 double charge, 00046 int iSpin, 00047 int iParity, 00048 int iConjugation, 00049 int iIsospin, 00050 int iIsospinZ, 00051 int gParity, 00052 const string & pType, 00053 int lepton, 00054 int baryon, 00055 int encoding, 00056 bool stable, 00057 double lifetime); 00058 }; 00059 00060 #endif
