Role of quarks in hadroproduction in high energy collisions

Abstract

Qualitative model for hadroproduction in high energy collisions considering two components ("thermal" and "hard") to hadroproduction is proposed. Inclusive pseudorapidity distributions, $d\sigma /d\eta$, and transverse momentum spectra, $d^2\sigma /(d\eta d{p}_T^2)$, measured by different collaborations are considered in terms of this model. The shapes of the pseudorapidity distributions agree with that one can expect from the qualitative picture introduced. Finally, the differences between charged particle spectra produced in inclusive and diffractive events are discussed and the absence of the "thermal" component in the latter is observed.

arXiv commentMore data on diffractive events has been considered, two plots added, new conclusions are made
