Semihard collisions in Monte Carlo quark-gluon string model

Abstract

The production of parton cascades, i.e., the hard parton scatterings with their subsequent decay, is introduced in the Monte Carlo quark-gluon string model. The influence of the semihard gluon collisions on observable characteristics of proton-antiproton interactions at energies reached at the CERN Super Proton Synchrotron and Fermilab Tevatron is examined within the eikonal approach allowing us to combine the soft and semihard gluon collisions.
