Systematic study of particle production inp+p (p¯)collisions via the HIJING model

We apply the newly developed HIJING Monte Carlo model to perform a systematic study of a broad range of data on $p+p\left(\overline{p}\right)$ collisions. The model combines a simple string phenomenology for $\mathrm{l}\mathrm{o}\mathrm{w}-p_T$ processes together with perturbative QCD for $\mathrm{h}\mathrm{i}\mathrm{g}\mathrm{h}-p_T$ processes. We emphasize the effects due to multiple-minijet production at collider energies. The energy and multiplicity dependence of charged particle rapidity and transverse momentum spectra, the Koba-Nielsen-Olesen violation of multiplicity distributions, and the two-particle correlation functions are shown to be simultaneously well accounted for with this model.
