Hadronic dissipative effects on transverse dynamics at RHIC
نویسنده
چکیده
We simulate the dynamics of Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC) with a hybrid model that treats the quark-gluon plasma macroscopically as an ideal fluid, but models the hadron resonance gas microscopically using a hadronic cascade. We find that much of the mass-ordering pattern for v2(pT ) observed at RHIC is generated during the hadronic stage due to build-up of additional radial flow. We also find that the mass-ordering pattern is violated for φ meson due to small interaction cross section in the hadron resonance gas.

Fe b 19 99 Analysis of reaction dynamics at RHIC in a combined parton / hadron transport approach
We introduce a transport approach which combines partonic and hadronic degrees of freedom on an equal footing and discuss the resulting reaction dynamics. The initial parton dynamics is modeled in the framework of the parton cascade model, hadronization is performed via a cluster hadroniza-tion model and configuration space coalescence, and the hadronic phase is described by a microscopic hadro...
متن کاملWhat can we learn from hydrodynamic analysis of elliptic flow ? ∗
Recently, physicists at Brookhaven National Laboratory made an announcement that “RHIC serves the perfect liquid” [ 1]. The agreement of hydrodynamic predictions [ 2] of integrated and differential elliptic flow and radial flow patterns with Au+Au data at RHIC energies [ 3, 4, 5, 6] is one of the main lines of the announcement. We first study the sensitivity of this conclusion to different hydr...
متن کاملPerfect fluidity of sQGP core and dissipative hadronic corona
We can establish a new picture, the perfect fluid sQGP core and the dissipative hadronic corona, of the space-time evolution of produced matter in relativistic heavy ion collisions at RHIC. It is also shown that the picture works well also in the forward rapidity region through an analysis based on a new class of the hydro-kinetic model and is a manifestation of deconfinement. The agreement of ...

Non-ideal fluid dynamics with cylindrical symmetry in transverse direction and longitudinal scaling flow is employed to simulate the space-time evolution of the quark-gluon plasma produced in heavy-ion collisions at RHIC energies. The dynamical expansion is studied as a function of initial energy density and initial time. A causal theory of dissipative fluid dynamics is used instead of the stan...
متن کاملGlobal Observables at RHIC
The first three measurements from the RHIC program were results on global observables: charged particle multiplicity (Nch), transverse energy (ET ) and elliptic flow (v2). They offer a look at the large-scale features of particle production in high-energy nuclear collisions, with particular insight into entropy production and collective behavior. Results from all of the RHIC experiments are dis...
