Role of quarks in hadroproduction in high energy collisions


الملخص بالإنكليزية

Qualitative model for hadroproduction in high energy collisions considering two components (thermal and hard) to hadroproduction is proposed. Inclusive pseudorapidity distributions, $dsigma/deta$, and transverse momentum spectra, $d^2sigma/(deta dp_T^2)$, 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.
