Pion, kaon, and (anti-)proton production in U+U Collisions at $\sqrt{s_{NN}}$ = 193 GeV measured with the STAR detector

Abstract

We present the first measurements of transverse momentum spectra of ${\pi }^{\pm }$, $K^{\pm }$, $p(\bar{p})$ at midrapidity ($|y|<0.1$) in U+U collisions at $\sqrt{s_{NN}}$ = 193 GeV with the STAR detector at the Relativistic Heavy Ion Collider (RHIC). The centrality dependence of particle yields, average transverse momenta, particle ratios and kinetic freeze-out parameters are discussed. The results are compared with the published results from Au+Au collisions at $\sqrt{s_{NN}}=$ 200 GeV in STAR. The results are also compared to those from A Multi Phase Transport (AMPT) model.
