High-energy behavior of the nuclear symmetry potential in asymmetric nuclear matter RID A-2398-2009

Chen, LW; Ko, Che Ming; Li, Ba. (American Physical Society, 2005)

Using the relativistic impulse approximation with empirical NN scattering amplitude and the nuclear scalar and vector densities from the relativistic mean-field theory, we evaluate the Dirac optical potential for neutrons ...

Charged particle rapidity distributions at relativistic energies

Lin, ZW; Pal, S.; Ko, Che Ming; Li, Ba; Zhang, B. (American Physical Society, 2001)

Using a multiphase transport model (AMPT), which includes both initial partonic and final hadronic interactions, we study the rapidity distributions of charged particles such as protons, antiprotons, pions, and kaons in ...

J/Psi suppression in ultrarelativistic nuclear collisions

Zhang, B.; Ko, Che Ming; Li, Ba; Lin, ZW; Sa, BW. (American Physical Society, 2000)

Using a multiphase transport model, we study the relative importance of J/psi suppression mechanisms due to plasma screening, gluon scattering, and hadron absorption in heavy ion collisions at the Relativistic Heavy Ion ...

Hadron production from quark coalescence and jet fragmentation

Greco, V.; Ko, Che Ming; Vitev, I. (American Physical Society, 2005)

Transverse momentum spectra of pions, protons, and antiprotons in Au+Au collisions at intermediate RHIC energy root s(NN)=62 GeV are studied in a model that includes both quark coalescence from the dense partonic matter ...
