8 Oct 2009 | | Abstract: | Directed flow of charged hadron and identified particles have been studied in
the framework of a multi-phase transport (AMPT) model, for
$^{197}$Au+$^{197}$Au collisions at $sqrt{s_{NN}}=$200, 130, 62.4, 39, 17.2
and 9.2 GeV. The rapidity, centrality and energy dependence of directed flow
for charged particles over a wide rapidity range are presented. AMPT model
gives the right $v_1(y)$ slope, as well as its trend as a function of energy,
while underestimate the magnitude. Within AMPT model, proton $v_1$ slope is
found to change its sign when the energy increases to 130 GeV - a feature that
is consistent with "anti-flow". The hadronic re-scattering is found having
little effect on $v_1$ at top RHIC energies. These studies can help us to
understand the collective dynamics at early time in relativistic heavy ion
collisions, and they can also be served as references for the RHIC Beam Energy
Scan program. | | Source: | arXiv, 0910.1400 | | Services: | Forum | Review | PDF | Favorites | |
