Note

It is possible for the user to define more particles or to redefine some characteristics of the particles currently defined in GEANT, but this must be done with extreme care. In particular, the mass and charge of most particles are stored independently in FLUKA, and any change made via GSPART will not affect these values. Removing particles from the list can lead to unpredictable results and it is strongly discouraged.

The user who needs more particles, or wants to partly override the standard values, can do that via the routines GSPART and GSDK.

All data taken from M. Aguilar Benitez [] and updated with the values of the PDG [].
