Scaling of elliptic flow, recombination, and sequential freeze-out of hadrons in heavy-ion collisions
(American Physical Society, 2010)
The scaling properties of elliptic flow of hadrons produced in ultrarelativistic heavy-ion collisions are investigated at low transverse momenta, p(T) less than or similar to 2 GeV. Utilizing empirical parametrizations of ...
Stress tensor and bulk viscosity in relativistic nuclear collisions
(American Physical Society, 2008)
We discuss the influence of different initial conditions for the stress tensor and the effect of bulk viscosity on the expansion and cooling of the fireball created in relativistic heavy ion collisions. In particular, we ...
Centrality dependence of charged hadron and strange hadron elliptic flow from root s(NN)=200 GeVAu+Au collisions
(American Physical Society, 2008)
We present STAR results on the elliptic flow upsilon(2) Of charged hadrons, strange and multistrange particles from,root s(NN) = 200 GeV Au+Au collisions at the BNL Relativistic Heavy Ion Collider (RHIC). The detailed study ...
Probing nuclear matter with jet conversions
(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 ...
Triangular flow in heavy ion collisions in a multiphase transport model
(American Physical Society, 2011)
We obtain a new set of parameters in a multiphase transport (AMPT) model that are able to describe both the charged particle multiplicity density and the elliptic flow measured in Au + Au collisions at center-of-mass energy ...
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 ...
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 ...
Long range rapidity correlations and jet production in high energy nuclear collisions
(American Physical Society, 2009)
The STAR Collaboration at the Relativistic Heavy Ion Collider presents a systematic study of high-transverse-momentum charged-di-hadron correlations at small azimuthal pair separation Delta phi in d+Au and central Au+Au ...
Decoherence and entropy production in relativistic nuclear collisions
(American Physical Society, 2009)
Short thermalization times of less than 1 fm/c for quark and gluon matter have been suggested by recent experiments at the Relativistic Heavy Ion Collider. It has been difficult to justify this rapid thermalization in ...
