PRODUCTION OF CUMULATIVE PARTICLES AND THE QUARK-GLUON STRING MODEL

Production of cumulative particles in nucleon-nucleus interactions is considered in the framework of the quark-gluon string model. Distribut ion of quarks in the nucleus is derived under the assumption that cohe rent clusters exist in the nucleus and their structure functions have Regge asymptotic behavior. Inclusive spectra of cumulative hadrons (K- mesons, pi-mesons, pBAR) are analyzed. It is shown that, in this model , the spectrum of cumulative K--mesons has a behavior similar to that of K+-mesons, as observed experimentally.
