// Hadron physics for the new physics list FTFP_BERT_ATL.
// This is a modified version of the FTFP_BERT hadron physics for ATLAS.
// The hadron physics of FTFP_BERT_ATL has the transition between Bertini
// (BERT) intra-nuclear cascade model and Fritiof (FTF) string model in the
// energy region [9, 12] GeV.
