Description
Various mechanisms potentially capable to tame the energy rise of interaction cross sections and of particle production in hadronic collisions are analysed. In particular, a phenomenological implementation of higher twist corrections to parton scattering processes, as realized in the QGSJET-III Monte Carlo generator, is described in some detail. The relation of the mechanism to ad hoc parametrizations of the energy-dependent transverse momentum cutoff for minijet production, commonly employed by general purpose Monte Carlo generators is discussed.
