The effect of triangular flow on di-hadron azimuthal correlations in relativistic heavy ion collisions
effect triangular flow di-hadron azimuthal correlations relativistic heavy ion collisions
2010/12/27
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 $\sqrt{...
Jets, Mach cone, hot spots, ridges, harmonic flow, dihadron and $\gamma$-hadron correlation in high-energy heavy-ion collisions
Jets Mach cone hot spots ridges harmonic flow dihadron correlation high-energy heavy-ion collisions
2010/12/29
Within the AMPT Monte Carlo model, hot spots in the initial transverse parton density are shown to lead to harmonic flows which all contribute to dihadron azimuthal correlation. The net back-to-back d...

Directed flow midrapidity heavy-ion collisions
2010/12/31
It was recently shown by Teaney and Yan that fluctuations in the initial geometry of a heavy ion collision generally result in a dipole asymmetry of the distribution of outgoing particles. This asymme...

2011/1/10
Assuming that the final state of hadronization takes place along the freezeout line, which is defined by a constant entropy density, the antiproton-to-proton ratios produced in heavy-ion collisions ar...
Collective flow and long-range correlations in relativistic heavy ion collisions
Collective flow long-range correlations relativistic heavy ion collisions
2010/12/29
Making use of recently released data on dihadron correlations by the STAR collaboration, I analyze the long-range ("ridge-like") part of these data and show that the dependence on both transverse mome...

The recently published first measurement of charged hadron multiplicity density at mid-rapidity $dN_{ch}/d\eta=1584 \pm 4 ({\rm stat.}) \pm 76 ({\rm sys.})$ in central $Pb+Pb$ collisions at $\sqrt{s} ...
QCD under magnetic field: chiral magnetic effect at heavy ion collisions

2011/1/10
In this talk, we report our recent studies for the chiral magnetic e ect, which signals the P- and CP-violations at heavy ion collisions. We compute the electric current and its correlations, induced ...

Nuclear absorption Lambda-bar/p-bar ratio heavy ion collisions
2010/12/27
An enhanced \lp\ ratio in heavy-ion relative to $p+p$ collisions has been proposed as one of the signatures for the Quark-Gluon Plasma (QGP) formation. A significantly large \Lp\ ratio of 3.5 has bee...

Identifying hadronic molecular states and/or hadrons with multi-quark components either with
or without exotic quantum numbers is a long standing challenge in hadronic physics. We suggest
that study...
