8  * The design of the StParticleDefinition class and all concrete
9  * classes derived from it is largely based on the design of the
10  * G4ParticleDefinition class from Geant4 (RD44).
11  * Although the code is in large parts different (modified or rewritten)
12  * and adapted to the STAR framework the basic idea stays the same.

17  * Revision 1.1 2010/01/28 20:01:00 jwebb
18  * Added two 'STAR' particle classes. The (fake) Dalitz particle, which
19  * is really just a pi0 with its Dalitz decay branch at 100%. It is added
20  * so the embedding team can access it by the geant ID defined in gstar_part.g.
21  * The hypertriton is also added.
22  *
23  * In both cases we define a fake PDG id in the header file StarPDGEncoding.hh.
