An updated description of heavy-hadron interactions in Geant-4

Abstract

Exotic stable massive particles (SMP) are proposed in a number of scenarios of physics beyond the Standard Model. LHC experiments are expected to be able both to detect and extract the quantum numbers of any SMP with masses around the TeV scale. An understanding of the interactions of SMPs in matter is required to optimise the detection methods and calculate acceptances in an SMP search. In this paper a regge-based model of R-hadron scattering is extended and implemented in Geant-4. In addition, the implications of R-hadron scattering for collider searches are discussed. © Springer-Verlag / Società Italiana di Fisica 2010.
