摘要

The pseudorapidity distributions of charged particles produced in p (p) over bar 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.
