Application of the multisource thermal model in pseudorapidity distributions of charged particles produced in pp? or pp collisions over an energy range from 0.053 to 7 TeV

摘要

The pseudorapidity distributions of charged particles produced in pp? or pp collisions over a center-of-mass energy range from 0.053 to 7 TeV have been studied by using the multisource thermal model. The difference between the rapidity and pseudorapidity for massive particles (pions) has been considered. The calculated results are found to be in agreement with the experimental data of the UA5, UA1, P238, CDF, CMS and ALICE Collaborations.
