(American Physical Society, 2005)The results from the STAR Collaboration on directed flow (v(1)), elliptic flow (v(2)), and the fourth harmonic (v(4)) in the anisotropic azimuthal distribution of particles from Au+Au collisions at root s(NN) = 200 GeV are ...
-
(American Physical Society, 2005)Charm elliptic flow in heavy-ion collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Assuming that the cross section for charm quark scattering with other light quarks is the same ...
-
(American Physical Society, 1994)We derive classically an expression for a hadron width in a two-phase region of hadron gas and quark-gluon plasma (QGP). The presence of QGP gives hadrons larger widths than they would have in a pure hadron gas. We find ...

(American Physical Society, 2010)We present the first measurements of identified hadron production, azimuthal anisotropy, and pion interferometry from Au + Au collisions below the nominal injection energy at the BNL Relativistic Heavy-Ion Collider (RHIC) ...
-
(American Physical Society, 2002)Using a multiphase transport model, we study J/psi production from interactions between charm and anticharm quarks in the initial parton phase and between D and (D) over bar mesons in the final hadron phase of relativistic ...
-
In the evolution of fireballs produced by Ulra-Relativistic High Energy Collisions, the introduction of a first-order phase transition between Quark Gluon Plasma (QGP) and hadronic matter phases was predicted to extend the ...
-
(American Physical Society, 2000)The cross sections for J/psi absorption by pi and rho mesons are studied in a meson-exchange model that includes not only pseudoscalar-pseudoscalar-vector-meson couplings but also three-vector-meson and four-point couplings. ...
-
(American Physical Society, 2000)To study heavy ion collisions at energies available from the Relativistic Heavy Ion Collider (RHIC), we have developed a multiphase transport model that includes both initial partonic and final hadronic interactions. ...

(American Physical Society, 2004)Higher-order anisotropic flows v(4) and v(6) of charged hadrons in heavy-ion collisions at the Relativistic Heavy Ion Collider are studied in a multiphase transport model that has previously been used successfully for ...

(American Physical Society, 2008)The photon bremsstrahlung rate from a quark jet produced in deep-inelastic scattering (DIS) off a large nucleus is studied in the collinear limit. The leading medium-enhanced higher twist corrections that describe the ...
-
(American Physical Society, 2004)The cross sections for production of the pentaquark baryon Xi(5)(+) from the reaction gammap-->K(0)K(0)Xi(5)(+) and of Xi(5)(--) from the reaction gamman-->K(+)K(+)Xi(5)(--) are evaluated in a hadronic model that includes ...
-
(American Physical Society, 2008)We discuss the flavor of leading jet partons as a valuable probe of nuclear matter. We point out that the coupling of jets to nuclear matter naturally leads to an alteration of jet chemistry even at high transverse momentum ...
-
(American Physical Society, 2004)The pseudorapidity asymmetry and centrality dependence of charged hadron spectra in d+Au collisions at roots(NN)=200 GeV are presented. The charged particle density at midrapidity, its pseudorapidity asymmetry, and centrality ...
-
(American Physical Society, 2010)A thermodynamic T-matrix approach for elastic two-body interactions is employed to calculate spectral functions of open and hidden heavy-quark systems in the quark-gluon plasma. This enables the evaluation of quarkonium ...
-
(American Physical Society, 2011)Identified charged pion, kaon, and proton spectra are used to explore the system size dependence of bulk freeze-out properties in Cu + Cu collisions at root s(NN) = 200 and 62.4 GeV. The data are studied with hydrodynamically ...
-
(2016-05-26)In this work, we examine properties of quantum chromodynamics (QCD) at moderate temperatures and density. These conditions are reached in the later stages of ultra-relativistic heavy-ion collisions after the matter has ...
-
(American Physical Society, 2005)Correlations in the hadron distributions produced in relativistic Au+Au collisions are studied in the discrete wavelet expansion method. The analysis is performed in the space of pseudorapidity (vertical bar eta vertical ...
