Study of transverse momentum distributions in p−Pb interactions at 0.9 TeV and 5.02 TeV

Abstract

This work is aimed to investigate the transverse momentum ([Formula: see text]) distributions of primary charged particles produced in p[Formula: see text][Formula: see text]Pb collisions at [Formula: see text][Formula: see text]0.9 TeV and 5.02 TeV. In this perspective, we have considered the pseudorapidity [Formula: see text] regions of [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] and the transverse momentum range of [Formula: see text]. In order to check the validity of simulation, we have compared the prediction of EPOS-1.99, EPOS-LHC and QGSJETII-04 models with the measurement of the [Formula: see text] distribution of ALICE experiment at [Formula: see text][Formula: see text]5.02 TeV for [Formula: see text], [Formula: see text], [Formula: see text], and with the CMS experiment for [Formula: see text]. We discovered that all the models overpredict the distribution of the experimental data for [Formula: see text][Formula: see text]5 GeV/c while presenting consistent result with each other at 0.9 TeV as well as 5.02 TeV. For [Formula: see text][Formula: see text]5 GeV/c, the models seem to be consistent with the experimental data where the EPOS-LHC describes both the ALICE and CMS data very well.
