Inclusion of transverse quark momenta in the quark-gluon string model (original) (raw)

1991, Zeitschrift für Physik C Particles and Fields

The dependence of distribution functions of quarks, antiquarks, diquarks and their fragmentation into hadrons on the transverse momentum kt is discussed in the frame of the quark-gluon string model. We then discuss the division of kt between 2n-quark-antiquark chains, or n-pomeron showers. Hadron and hadron-nuclear processes p-p, p-A, K +-p, K +-A are analysed. A strong dependence of the observed values on the number n is derived by this method, which is of special importance for the analysis of hadron-nucleus collisions. Our method is compared with the regular kt division method.
