On the Use of the Tsallis Distribution at LHC Energies
arXiv:1609.02289 · doi:10.1088/1742-6596/779/1/012079
Abstract
Numerous papers have appeared recently showing fits to transverse momentum () spectra measured at the Large Hadron Collider (LHC) in proton - proton collisions.This talk focuses on the fits extending to very large values of the transverse momentum with values up to 200 GeV/c as measured by the ATLAS and CMS collaborations at = 0.9 and 7 TeV. A thermodynamically consistent form of the Tsallis distribution is used for fitting the transverse momentum spectra at mid-rapidity. The fits based on the proposed distribution provide an excellent description over 14 orders of magnitude. Despite this success, an ambiguity is noted concerning the determination of the parameters in the Tsallis distribution. This prevents drawing firm conclusions as to the universality of the parameters appearing in the Tsallis distribution.
