With the new viscous hydrodynamic + hadron cascade hybrid code VISHNU, a rather precise (O(25%)) extraction of the QGP shear viscosity (eta/s)_QGP from heavy-ion elliptic flow data is possible if the ...
Initial fluctuation and dihadron and $γ$-hadron correlations in high-energy heavy ion collisions
Initial fluctuation dihadron $γ$-hadron
2011/7/21
Fluctuations in initial parton density give rise to fluctuating geometrical shapes and hot spots in high energy heavy ion collisions.
Nuclear collision in strong magnetic field
Nuclear collision strong magnetic field isospin physics
2011/7/20
We studied nucleus-nucleus collision in strong magnetic field based on a transport model. It is found that neutrons and protons can be separated from a nucleus by strong magnetic field and neutron-ric...
Low energy ω(\to π^0 γ) meson photoproduction in the nucleus
ω meson photoproduction π0γ invariant mass distribution
2011/7/20
The $\pi^0 \gamma$ invariant mass distribution spectra in the $ (\gamma, \pi^0\gamma) $ reaction were measured by TAPS/ELSA collaboration to look for the hadron parameters of the $\omega$ meson in Nb ...
Nuclear dynamics at the balance energy of mass asymmetric colliding nuclei
heavy-ion collisions uantum molecular dynamics (QMD) model
2011/7/20
Using the quantum molecular dynamics model, we study the nuclear dynamics at the balance energy of mass asymmetric colliding nuclei by keeping the total mass of the system fixed as 40, 80, 160, and 24...
Multifragmentation at the balance energy of mass asymmetric colliding nuclei
asymmetric colliding nuclei balance energy
2011/7/20
Using the quantum molecular dynamics model, we study the role of mass asymmetry of colliding nuclei on the fragmentation at the balance energy and on its mass dependence. The study is done by keeping ...
Momentum dependence of the symmetry potential and its influence on nuclear reactions
LQMD model ass splitting omentum-dependent potential
2011/7/20
A Skyrme-type momentum-dependent nucleon-nucleon force distinguishing isospin effect is parameterized and further implemented in the Lanzhou Quantum Molecular Dynamics (LQMD) model for the first time,...
Viscous Hydrodynamic Evolution with Non-Boost Invariant Flow for the Color Glass Condensate
Viscous Hydrodynamic Color Glass Condensate
2011/7/20
The Large Hadron Collider (LHC) experiments have revealed that the predictions of the color glass condensate (CGC) tend to underestimate the multiplicity at mid-rapidity.
Directed, Elliptic and Triangular Flows in Asymmetric Heavy Ion Collisions
asymmetric nuclear collisions
2011/7/20
In this paper we propose to thoroughly investigate asymmetric nuclear collisions both in the fixed target mode at the laboratory energy below 5 GeV per nucleon and in the collider mode with a center o...
Recent lattice QCD calculations have reported evidence for the existence of a bound state with strangeness -2 and baryon number 2 at quark masses somewhat higher than the physical values.
Momentum dependence of drag coefficients and heavy flavour suppression in quark gluon plasma
Momentum dependence heavy flavour suppression
2011/7/20
The momentum dependence of the drag coefficient of heavy quarks propagating through quark gluon plasma (QGP) has been evaluated. The results have been used to estimate the nuclear suppression factor o...
Proton inelastic diffraction by a black nucleus and the size of excited nuclei
black nucleus Proton inelastic diffraction
2011/7/20
We systematically derive a length scale characterizing the size of a low-lying, beta stable nucleus from empirical data for the diffraction peak angle in the proton inelastic differential cross sectio...
The dynamics of partons, hadrons and strings in relativistic nucleus-nucleus collisions is analyzed within the novel Parton-Hadron-String Dynamics (PHSD) transport approach, which is based on a dynami...
High-spin structure of odd $^{71-81}$Ga isotopes with shell model

2011/7/20
The recently measured experimental data of Argonne National Laboratory for high-spin states in neutron-rich $^{71,73,75,77}$Ga isotopes have been interpreted in the framework of large-scale shell mode...
