Description
The mean $p_{\rm{T}}$ 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 poster we present the first efficiency corrected charged particle event-by-event mean $p_{\rm{T}}$ fluctuations from central Au+Au collisions at $\sqrt{s_{\rm{NN}}}$ = 3 GeV in the STAR experiment. Mean $p_{\rm{T}}$ fluctuations are calculated for different acceptance windows in pseudorapidity and compared with the previous BES-I results at $\sqrt{s_{\rm{NN}}}$ = 19.6, 62.4, 130, and 200 GeV, as well as the results from transport model a t$\sqrt{s_{\rm{NN}}}$ = 3 GeV. We also discuss the effects of primordial protons on the mean pT fluctuations.
