Detailed Description

Physics list based on CRMC for high-energy hadron-hadron interactions.

This physics list inherits from FTFP_BERT and above athreshold energy it replaces the FTF model for hadron-hadron interactions with one of the models supported by CRMC. The model and the energy thresholds can be set by means of datacard commands. Default values are DPMJET-3.06 and 300 GeV.

void GGSCRMCPhysicsList::ConstructProcess

(

)

Constructs the physical processes.

Calls FTFP_Bert::ConstructProcess and then creates the CRMC model.
