Abstract: The Tsallis distribution was introduced in 1988 by Constantin Tsallis and has been used in many fields of physics. It has been widely used in high energy physics by the large experimental collaborations (PHENIX, STAR, ALICE, ATLAS, CMS, ...) mainly to describe transverse momentum distributions. Despite this, it has not received much attention from the theoretical high energy physics community. In this talk we will present a short review of the Tsallis distribution focusing on the use in high energy physics. A proposal will be considered to bring consistency to the values of the Tsallis parameter $q$ and the corresponding temperature $T$.

In CMS, the spectra of charged or identified hadrons were fit by a Tsallis function, which empirically describes both the low-pt exponential and the high-pt power-law behaviours. The success of this parametrization will be demonstrated through various examples.

PHENIX has measured production spectra for a large collection of identified hadrons in p+p and d+Au collisions at 200 GeV. We demonstrate that all production spectra can be well fit to Tsallis distribution in the whole range of measurements. We also present analysis of fit parameters in dependence on particle mass.
