Characterizing Proton-Proton Collisions at the Large Hadron Collider with Thermal Properties

High-multiplicity proton-proton (pp) collisions at the Large Hadron Collider (LHC) energies have created a new domain of research to look for a possible formation of quark-gluon plasma in these events. In this paper, we estimate various thermal properties of the matter formed in pp collisions at the LHC energies, such as mean free path, isobaric expansivity, thermal pressure, and heat capacity using a thermodynamically consistent Tsallis distribution function. Particle species-dependent mean free path and isobaric expansivity are studied as functions of final state charged particle multiplicity for pp collisions at the center-of-mass energy root s = 7 TeV. The effects of degree of non-extensivity, baryochemical potential, and temperature on these thermal properties are studied. The findings are compared with the theoretical expectations.

Automated summary

This paper explores the thermal properties of matter formed in proton-proton collisions at LHC energies, such as mean free path, isobaric expansivity, and thermal pressure, utilizing a thermodynamically consistent Tsallis distribution function. The study investigates the particle species-dependent mean free path and isobaric expansivity as functions of final state charged particle multiplicity for pp collisions at a center-of-mass energy root s = 7 TeV. The effects of non-extensivity, baryochemical potential, and temperature on these thermal properties are also examined and compared with theoretical expectations.
