Single and double pi^{-}/pi^{+} ratios in heavy-ion reactions as probes of the high-density behavior of the nuclear symmetry energy
Gao-Chan Yong, Bao-An Li, Lie-Wen Chen +1
Based on an isospin- and momentum-dependent hadronic transport model IBUU04, effects of the nuclear symmetry energy on the single and double pi^{-}/pi^{+}ratios in central reaction…
Rapidity and system size dependence of anisotropic flows in relativistic heavy ion collisions
Che Ming Ko, Lie-Wen Chen
We report results from a multiphase transport (AMPT) model on the rapidity and system size dependence of charged hadron anisotropic flows in nuclear collisions at the Relativistic…
Double neutron/proton ratio of nucleon emissions in isotopic reaction systems as a robust probe of nuclear symmetry energy
Bao-An Li, Lie-Wen Chen, Gao-Chan Yong +1
The double neutron/proton ratio of nucleon emissions taken from two reaction systems using four isotopes of the same element, namely, the neutron/proton ratio in the neutron-rich s…
Charm elliptic flow in Au+Au collisions at RHIC
Bin Zhang, Lie-Wen Chen, Che-Ming Ko
Using the perturbative method for the simulation of charmed particles, the dynamical origin of charm quark elliptic flow is studied in the framework of a multi-phase transport (AMP…
Nuclear matter symmetry energy and the neutron skin thickness of heavy nuclei
Lie-Wen Chen, Che Ming Ko, Bao-An Li
Correlations between the thickness of the neutron skin in finite nuclei and the nuclear matter symmetry energy are studied in the Skyrme Hartree-Fock model. From the most recent an…
Nucleon-nucleon cross sections in neutron-rich matter and isospin transport in heavy-ion reactions at intermediate energies
Bao-An Li, Lie-Wen Chen
Nucleon-nucleon (NN) cross sections are evaluated in neutron-rich matter using a scaling model according to nucleon effective masses. It is found that the in-medium NN cross sectio…
