We report a measurement of the longitudinal double-spin asymmetry A_LL and the differential cross section for inclusive mid-rapidity jet production in polarized proton collisions at $\\sqrt{s}$=200 GeV. The cross section data cover transverse momenta 5 < pT < 50 GeV/c and agree …

We present STAR measurements of the azimuthal anisotropy parameter $v_2$ for pions, kaons, protons, $\\Lambda$, $\\bar{\\Lambda}$, $\\Xi+\\bar{\\Xi}$, and $\\Omega + \\bar{\\Omega}$, along with $v_4$ for pions, kaons, protons, and $\\Lambda + \\bar{\\Lambda}$ at mid-rapidity for Au+Au collisions at $\\sqrt{s_{_{NN}}}=62.4$ and 200 GeV. …

The short-lived K(892)* resonance provides an efficient tool to probe properties of the hot and dense medium produced in relativistic heavy-ion collisions. We report measurements of K* in {radical}s{sub NN} = 200 GeV Au+Au and p+p collisions reconstructed via its hadronic decay …

The degradation of Lambda transverse polarization produced in S + Pb central collisions at energy 200 GeV per nucleon has been studied in detail. The S + Pb central collision events have been generated using Monte-Carlo generator-LUCIAE at 200 GeV per nucleon, …
