Mean pT fluctuations in 3.0 GeV fixed-target collisions from the STAR experiment

ORAL

Abstract

The mean pT fluctuations in heavy-ion collisions can be related to temperature fluctuations which quantify the specific heat of the system. Any deviations from the Hadron

Resonance Gas model as a function of the incident energy can be interpreted as a possible signal of criticality. In this talk we present the first efficiency corrected charged particle

event-by-event mean pT fluctuations from central Au+Au collisions at √sNN = 3 GeV in the STAR experiment. Mean pT fluctuations are calculated for different acceptance windows in

pseudorapidity and compared with the previous BES-I results at √sN N = 19.6, 62.4, 130, and 200 GeV, as well as the results from transport model at √sN N = 3 GeV.

We also discuss the effects of primordial protons on the mean pT fluctuations.
