Energy Dependent Growth of Nucleon and Inclusive Charged Hadron Distributions

Original · EN

In the Color Glass Condensate formalism, charged hadron pₜ distributions in p+p collisions are studied by considering an energy-dependent broadening of nucleon's density distribution. Then, in the Glasma flux tube picture, the n-particle multiplicity distributions at different pseudo-rapidity ranges are investigated. Both of the theoretical results show good agreement with the recent experimental data from ALICE and CMS at √s=0.9, 2.36, 7 TeV. The predictive results for pₜ and multiplicity distributions in p+p and p+Pb collisions at the Large Hadron Collider are also given in this paper.
