Chen, LW; Ko, Che Ming. (American Physical Society, 2006)The anisotropic flow of charged hadrons in asymmetric Cu+Au collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Compared with previous results for symmetric Au+Au collisions, charged ...

Li, GQ; Ko, Che Ming. (American Physical Society, 1996)We study antikaon flow in heavy-ion collisions at SIS energies based on the relativistic transport model (RVUU 1.0). The production of antikaons from both baryon-baryon and pion-baryon collisions are included. Taking into ...

LI, GQ; Ko, Che Ming. (American Physical Society, 1994)Antiproton production in Ni+Ni collisions at 1.85 GeV/nucleon is studied in the relativistic Vlasov-Uehling-Uhlenbeck model. The self-energies of the antiproton are determined from the nucleon self-energies by the G-parity ...

Lin, ZW; Ko, Che Ming. (American Physical Society, 2001)We show that omega (B) or omega ((B) over bar), the squared baryon or antibaryon number fluctuation per baryon or antibaryon, is a possible signature for the quark-gluon plasma that is expected to be created in relativistic ...

Zhang, B.; Chen, LW; Ko, Che Ming. (American Physical Society, 2005)Charm elliptic flow in heavy-ion collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Assuming that the cross section for charm quark scattering with other light quarks is the same ...

Lee, S. H.; Ko, Che Ming. (American Physical Society, 2003)The mass shift of charmonium states in nuclear matter is studied in the perturbative QCD approach. The leading-order effect due to the change of gluon condensate in nuclear matter is evaluated using the leading-order QCD ...

Liu, W.; Ko, Che Ming. (American Physical Society, 2003)Using hadronic Lagrangians that include the interaction of pentaquark Theta(+) baryon with K and N, we evaluate the cross sections for its production from meson-proton, proton-proton, and photon-proton reactions near ...
-
Xu, Jun; Ko, Che Ming. (American Physical Society, 2010)By assuming that the isospin- and momentum-dependent MDI interaction has a form similar to the Gogny-like effective two-body interaction with a Yukawa finite-range term and the momentum dependence originates only from the ...
-
Oh, Yongseok; Lin, Zi-Wei; Ko, Che Ming. (American Physical Society, 2009)The hadronic transport model ART is extended to include the production and annihilation of deuterons via the reactions BB dM, where B and M stand for baryons and mesons, respectively, as well as their elastic scattering ...
-
Lin, ZW; Ko, Che Ming. (American Physical Society, 2003)Using a multiphase transport model, we study pseudorapidity distributions and transverse momentum spectra in deuteron-gold collisions at RHIC. We find that final-state partonic and hadronic interactions affect the transverse ...
-
Song, C.; Ko, Che Ming. (American Physical Society, 1996)Dilepton production from resonance scattering in hot hadronic matter is studied. Including the widths of these resonances, which enhance the phase space for dilepton production, we find that the production rate is significantly ...

Song, Taesoo; Han, Kyong Chol; Ko, Che Ming. (American Physical Society, 2011)Assuming that in the hot dense matter produced in relativistic heavy-ion collisions, the energy density, entropy density, and pressure as well as the azimuthal and space-time rapidity components of the shear tensor are ...
-
Greco, V.; Ko, Che Ming. (American Physical Society, 2004)Within the quark coalescence model, we study effects of resonance decays, and of the quark momentum distribution in hadrons, on the elliptic flows of stable hadrons. We find that, with the exception of rho-meson decays, ...

Song, C. S.; Xia, P. W.; Ko, Che Ming. (American Physical Society, 1995)Effects of (N) over bar N polarization on vector meson (rho and omega) masses at finite temperature are studied. Including a reduced nucleon mass in a hot matter, we find that the reduction of vector meson masses due to ...

Effects of triangular flow on di-hadron azimuthal correlations in relativistic heavy ion collisions Xu, Jun; Ko, Che Ming. (American Physical Society, 2011)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 root s(NN) = 200 GeV and ...

Oh, Yongseok; Ko, Che Ming. (American Physical Society, 2007)Using a dynamical model based on the NN -> d pi,NNN -> dN, and NN pi -> d pi reactions and measured proton and pion transverse momentum spectra and elliptic flows, we study the production of deuterons and their elliptic ...

Li, Ba0-An; Ko, Che Ming. (American Physical Society, 1995)We present the detail of a newly developed relativistic transport model (ART 1.0) for high energy heavy-ion collisions. Using this model, we first study the general collision dynamics between heavy ions at the AGS energies. ...
