Abstract

We have studied the distributions of the yield of primary charged particles produced in the asymmetric [Formula: see text]–[Formula: see text] collisions at [Formula: see text] for the three pseudorapidity regions: [Formula: see text] and [Formula: see text] and the transverse momentum range of [Formula: see text]. Heavy ion jet interaction generator (HIJING) and Ultra relativistic quantum molecular dynamics (UrQMD) models are used to produce simulated data and the results are compared with the CMS and ATLAS data. The comparison of models and data shows the existence of high [Formula: see text] area with boundary values that depend upon pseudorapidity ([Formula: see text]). At high [Formula: see text] values, the behavior of the distributions shows some universality, which does not depend upon the models. The reason of the universality could be the string dynamics for the parton hadronization at high [Formula: see text] values.
