Semihard hadron processes and the quark-gluon string model

A new approach to the analysis of soft and semihard hadron processes is suggested. In the framework of the Quark-Gluon String Model, the interaction of quarks from colliding hadrons is calculated as the exchange by nonperturbative gluons, for which the cut-off parameter in the gluonic propagator is included. This modification has allowed us to analyse the inclusive hadron spectra in hadron collisions at transverse momenta up to 3–4 GeV/c.
