From unintegrated gluon distributions to particle production in hadronic collisions at high energies
Abstract
Description
The inclusive distributions of gluons and pions for high-energy NN collisions are calculated. The results for several unintegrated gluon distributions (UGD's) from the literature are compared. We find huge differences in both rapidity and $p_t$ of gluons and $π$'s in NN collisions for different models of UGD's. The Karzeev-Levin UGD gives good description of momentum distribution of charged hadrons at midrapidities. We find that the gluonic mechanism discussed does not describe the inclusive spectra of charged particles in the fragmentation region.
