We present two-particle $p_{rm t}$ correlations as a function of event centrality for Au+Au collisions at $sqrt{s_{rm NN}}$ = 7.7, 11.5, 14.5, 19.6, 27, 39, 62.4, and 200 GeV at the Relativistic Heavy Ion Collider using the STAR detector. These results are compared to previous measurements from CERES at the Super Proton Synchrotron and from ALICE at the Large Hadron Collider. The data are compared with UrQMD model calculations and with a model based on a Boltzmann-Langevin approach incorporating effects from thermalization. The relative dynamical correlations for Au+Au collisions at $sqrt{s_{rm NN}}$ = 200 GeV show a power law dependence on the number of participant nucleons and agree with the results for Pb+Pb collisions at $sqrt{s_{rm NN}} = 2.76~ {rm TeV}$ from ALICE. As the collision energy is lowered from $sqrt{s_{rm NN}}$ = 200 GeV to 7.7 GeV, the centrality dependence of the relative dynamical correlations departs from the power law behavior observed at the higher collision energies. In central collisions, the relative dynamical correlations increase with collision energy up to $sqrt{s_{rm NN}}$ = 200 GeV in contrast to previous measurements that showed little dependence on the collision energy.
We report high statistics measurements of inclusive charged hadron production in Au+Au and p+p collisions at sqrtsNN=200 GeV. A large, approximately constant hadron suppression is observed in central Au+Au collisions for $5ltpTlt12$ GeV/c. The collis
The two-particle angular correlation functions, $R_2$, of pions, kaons, and protons in Au+Au collisions at $sqrt{s_{NN}}=$ 7.7, 11.5, 14.5, 19.6, 27, 39, 62.4, and 200 GeV were measured by the STAR experiment at RHIC. These correlations were measured
We present results from a harmonic decomposition of two-particle azimuthal correlations measured with the STAR detector in Au+Au collisions for energies ranging from $sqrt{s_{NN}}=7.7$ GeV to 200 GeV. The third harmonic $v_3^2{2}=langle cos3(phi_1-ph
We report the energy dependence of mid-rapidity (anti-)deuteron production in Au+Au collisions at $sqrt{s_text{NN}} = $7.7, 11.5, 14.5, 19.6, 27, 39, 62.4, and 200 GeV, measured by the STAR experiment at RHIC. The yield of deuterons is found to be we
Local parity-odd domains are theorized to form inside a Quark-Gluon-Plasma (QGP) which has been produced in high-energy heavy-ion collisions. The local parity-odd domains manifest themselves as charge separation along the magnetic field axis via the
