Studying of final states in p-Au and p-Pb collisions

TL;DR

This study uses PYTHIA8.2 to simulate p-Au and p-Pb collisions at TeV energies, analyzing final states and the effects of impact parameter correlations on particle production.

Contribution

It introduces an improved phenomenological model within PYTHIA8.2 that accounts for impact parameter correlations and diffractive processes in heavy ion collision simulations.

Findings

Impact parameter correlations significantly affect production cross sections.

Transverse momentum and rapidity distributions of K-mesons and Lambda baryons were obtained.

The model provides insights into soft and hard subprocess contributions in proton-ion collisions.

Abstract

In the framework of PYTHIA8.2 program we considered p-Pb and p-Au heavy ion collisions at the energy of 5.02 TeV and 8 TeV. The advantage of this program is in the combining of several nucleon-nucleon collisions into one heavy ion collision, based on phenomenological treatment of a hadron as a vortex line in a color superconducting medium, the consistent treatment of the central rapidity region with improvements of Glauber-like model where diffractive excitation processes are taken into account. We have considered the influence of impact parameter correlations on the production cross sections of p-Pb and p-Au processes to estimate the influence of hard and soft subprocesses on basic hadronic final-state properties in proton-ion collisions. Using these characteristics based on semi-hard multiparton interaction model we received the transverse momentum and rapidity distributions of K-meson and Lambda baryon at the energy of 5.02 TeV and 8.14 TeV.
