On violation of Feynman scaling law in the framework of dual parton model

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The violation of scaling in the central- and fragmentation regions for nucleon-antinucleon collision is studied in the framework of the dual parton model. The results of calculations are compared with data. The formulae for the preasymptotic behavior of inclusive spectra in the central region are obtained. It is shown that the analytical form of the preasymptotic behavior is determined by the shape of the momentum distribution functions atx=0. The comparison with the corresponding results of the quark-gluon string model is given. Some problems concerning the calculation of the momentum distribution functions are considered.
