Hadronic collisions: physics, models and event generators

Models and event generators for hadronic collisions belong to the basic building blocks of hadron cascade calculations to simulate radiation problems around high energy accelerators and to simulate the Cosmic Ray cascade in the atmosphere, within the Earth or within space stations. The models for hadronic collisions have to provide the produced hadrons preferably in the form of Monte Carlo events as well as the inelastic cross sections of the collisions considered. The event generators of interest for our applications have to provide minimum bias events, not only events for selected (hard) collisions. (orig.)
