The Tsallis Distribution at Large Transverse Momenta

TL;DR

This paper demonstrates that the Tsallis distribution effectively models charged particle transverse momentum distributions in proton-proton collisions at LHC energies, covering a vast range of data, and compares two versions of the distribution.

Contribution

It compares two versions of the Tsallis distribution and confirms the thermodynamically consistent version yields a temperature consistent with previous studies.

Findings

Tsallis distribution fits data over 14 orders of magnitude

Thermodynamically consistent version yields T = 74 +/- 13 MeV

Results agree with previous lower transverse momentum analyses

Abstract

Fits to the transverse momentum distributions of charged particles produced in p - p collisions at LHC energies based on the Tsallis distribution have been shown to work over 14 orders of magnitude. Two versions of the Tsallis distribution are compared and discussed, the thermodynamically consistent version leads to a temperature of T = 74 +/- 13 MeV at the highest beam energy, a result which is in agreement with previous analyses done with lower transverse momentum data.
