Peculiarities of nonhamiltonian p-barp interactions at 22.4 GeV/c

The longitudinal and transverse momentum distributions of protons and π± mesons produced in p-barp- and pp-interactions at close energy (22-24 GeV) are compared. The existence of a difference between these distributions, both for protons at limited momenta (plab<1.2 GeV/c) and for π+ mesons accompanying them, is shown. The observed difference for protons increase with increasing the multiplicity of charged particles. It has been shown that the observed peculiarities of nonannihilation p-barp-interactions are not described by the LUND model, but some of them can be understood with the aid of the dual parton model diagrams
