Experimental Physics List QBBC V Ivanchenko CERN EMSU

Experimental Physics List QBBC V. Ivanchenko CERN, EMSU 10 th Geant 4 Workshop, 9 -14 October, Lisbon, Portugal QBBC 10. 2006 V. Ivanchenko

Motivation ► Shower shape problem requires experimental Physics List for exercises, which do not effect LHEP, QGSP… ► An attempt to create Physics Lists free of LHEP components § LHEP is a part of all 20 Physics. Lists ► Exercise different ways of configuration ► Exercise new models QBBC 10. 2006 V. Ivanchenko 2

QBBC Default ► QGSC for high energy: p, n, π± ► FTFC for K± , pbar, nbar ► LHEP for the rest ► Binary for p, n ► Bertini for π±, K± , Λ, Σ ► CHIPS for pbar, nbar, … QBBC 10. 2006 V. Ivanchenko 3

Hadronic Benchmark #5 (D. Wright) LHEP is equal to QGSP ► QBBC is very off ► 1 st interaction likely is very important ► QGS angular distribution is problematic ► HARP data! ► QBBC 10. 2006 V. Ivanchenko 7

Personal Current Point of View ► Keep Physics Lists as it is for December § Only minor improvement: merge 20 zero size libraries into 1 ► For next year plan inter-category project § Formulate and agree on requirements § Do design using Rose § Implementation only in second part of the next year not earlier QBBC 10. 2006 V.
