Charged particle rapidity distributions at relativistic energies
(American Physical Society, 2001)
Using a multiphase transport model (AMPT), which includes both initial partonic and final hadronic interactions, we study the rapidity distributions of charged particles such as protons, antiprotons, pions, and kaons in ...
Probing the softest region of the nuclear equation of state
(American Physical Society, 1998)
An attractive, energy-dependent mean-field potential for baryons is introduced in order to generate a soft region in the nuclear equation of state, as suggested by recent lattice QCD calculations of baryon-free matter at ...
Bottomonium production at root s(NN)=200 GeV and root s(NN)=5.5 TeV
(American Physical Society, 2006)
Properties of bottomonia (Upsilon,chi(b), and Upsilon ') in the quark-gluon plasma (QGP) are investigated by assessing inelastic reaction rates and their interplay with open-bottom states (b quarks or B mesons) and color ...
Charmonium in medium: From correlators to experiment
(American Physical Society, 2010)
We set up a framework in which in-medium charmonium properties are constrained by thermal lattice quantum chromodynamics and subsequently implemented into a thermal rate equation enabling the comparison with experimental ...
Charged and strange hadron elliptic flow in Cu plus Cu collisions at root s(NN)=62.4 and 200 GeV
(American Physical Society, 2010)
We present the results of an elliptic flow, v(2), analysis of Cu + Cu collisions recorded with the solenoidal tracker detector (STAR) at the BNL Relativistic Heavy Ion Collider at root s(NN) = 62.4 and 200 GeV. Elliptic ...
Directed flow in Au plus Au collisions at root s(NN)=62.4 GeV
(American Physical Society, 2006)
We present the directed flow (v(1)) measured in Au+Au collisions at root s(NN)=62.4 GeV in the midpseudorapidity region parallel to eta parallel to < 1.3 and in the forward pseudorapidity region 2.5 <parallel to eta parallel ...
Elliptic flow from two- and four-particle correlations in Au+Au collisions at root s(NN)=130 GeV
(American Physical Society, 2002)
Elliptic flow holds much promise for studying the early-time thermalization attained in ultrarelativistic nuclear collisions. Flow measurements also provide a means of distinguishing between hydrodynamic models and ...
J/psi production at high transverse momenta in p plus p and Cu plus Cu collisions at root s(NN)=200 GeV
(American Physical Society, 2009)
The STAR Collaboration at the Relativistic Heavy Ion Collider presents measurements of J/psi e(+) e(-) at midrapidity and high transverse momentum (pT > 5 GeV/c) in p + p and central Cu + Cu collisions at root s(NN) = 200 ...
Rho Meson in Dense Hadronic Matter
(American Physical Society, 1992)
The spectral function of a rho meson that is at rest in dense hadronic matter and couples strongly to the pion is studied in the vector dominance model by including the effect of the delta-hole polarization on the pion. ...
Formation and Decay of Toroidal and Bubble Nuclei and the Nuclear-Equation of State
(American Physical Society, 1993)
Multifragmentation, following the formation of toroidal and bubble nuclei, is observed with an improved Boltzmann-Uehling-Uhlenbeck model for central Mo-92 + Mo-92 collisions. With a stiff equation of state, simultaneous ...
