DUAL PARTON MODEL OF INELASTIC PP-INTERACTIONS AND CASCADE BREAKING OF STRING

A new cascade model of string breaking with 6 free parameters is const ructed. The dual parton model of inelastic pp-collisions, which uses t he supposed model of breaking of string, agrees well with the wide set of the experimental data at ISR energies, including the multiplicity, rapidity and transverse momentum distributions, the different correla tions and the production cross sections of baryons, antibaryons, stran ge particles and resonances. For the fitted values of the free paramet ers, the scaling functions of the model of string breaking are similar to the hadron structure functions. The inability of the dual parton m odel to explain the rise of the average transverse momentum with multi plicity at the SPS collider energies is discussed.
