(American Physical Society, 2006)The anisotropic flow of charged hadrons in asymmetric Cu+Au collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Compared with previous results for symmetric Au+Au collisions, charged ...

(American Physical Society, 2009)We present measurements of net charge fluctuations in Au+Au collisions at s(NN)=19.6, 62.4, 130, and 200 GeV, Cu+Cu collisions at s(NN)=62.4 and 200 GeV, and p+p collisions at s=200 GeV using the dynamical net charge ...

(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, 2009)The hadronic transport model ART is extended to include the production and annihilation of deuterons via the reactions BB dM, where B and M stand for baryons and mesons, respectively, as well as their elastic scattering ...

Effects of triangular flow on di-hadron azimuthal correlations in relativistic heavy ion collisions (American Physical Society, 2011)Using the AMPT model for relativistic heavy ion collisions, we have studied the di-hadron azimuthal angular correlations triggered by emitted jets in Au + Au collisions at center-of-mass energy root s(NN) = 200 GeV and ...

(American Physical Society, 2007)Using a dynamical model based on the NN -> d pi,NNN -> dN, and NN pi -> d pi reactions and measured proton and pion transverse momentum spectra and elliptic flows, we study the production of deuterons and their elliptic ...

(American Physical Society, 2005)We present the first large-acceptance measurement of event-wise mean transverse momentum fluctuations for Au-Au collisions at nucleon-nucleon center-of-momentum collision energy root s(NN) = 130 GeV. The observed ...

(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 ...
-
(American Physical Society, 2005)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 root s(NN)=200 GeV Au+Au and p+p ...

(American Physical Society, 1999)Using a relativistic transport model, we study the azimuthal momentum asymmetry of kaons with fixed transverse momentum, i.e., the differential flow, in heavy-ion collisions at beam momentum of 6 GeV/c per nucleon, available ...
-
(American Physical Society, 1996)Within the framework of a relativistic transport model (ART) for heavy-ion collisions at AGS energies, we examine the effects of a kaon dispersion relation on the transverse flow of kaons and their transverse momentum and ...
-
(American Physical Society, 2004)Transverse energy (ET) distributions have been measured for Au+Au collisions at roots(NN)=200 GeV by the STAR Collaboration at RHIC. E-T is constructed from its hadronic and electromagnetic components, which have been ...
-
(American Physical Society, 1993)In the linear chiral perturbation theory, both kaon and antikaon masses decrease in dense matter. There is also a repulsive vector potential for the kaon and an attractive one for the antikaon. With these effects included ...

(American Physical Society, 2006)Measurements of two-particle correlations on angular difference variables eta(1)-eta(2) (pseudorapidity) and phi(1)-phi(2) (azimuth) are presented for all primary charged hadrons with transverse momentum 0.15 <= p(t)<= 2 ...
-
(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, 2003)Using a covariant coalescence model, we study hadron production in relativistic heavy ion collisions from both soft partons in the quark-gluon plasma and hard partons in minijets. Including transverse flow of soft partons ...

(American Physical Society, 2002)The elliptic flow in heavy ion collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. By converting the strings in the high energy density regions into partons, we find that the final ...

(American Physical Society, 2006)Based on the phase-space information obtained from a multiphase transport model within the string-melting scenario for strange and antistrange quarks, we study the yields and transverse-momentum spectra of phi mesons and ...

(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 ...
