We present the first measurements of transverse momentum spectra of $$π^±, K^±, p(\overline{p})$$ at midrapidity ($|y|$ < 0.1) in $$\cup + \cup$$ 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 freezeout 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.
