    • Cross section for charmonium absorption by nucleons 
      Liu, W.; Ko, Che Ming; Lin, ZW. (American Physical Society, 2002)
      The cross section for J/psi absorption by nucleons is studied using a gauged SU(4) hadronic Lagrangian but with empirical particle masses, which has been used previously to study the cross sections for J/psi absorption by ...
    • Hadron Widths in Mixed-Phase Matter 
      Seibert, D.; Ko, Che Ming. (American Physical Society, 1994)
      We derive classically an expression for a hadron width in a two-phase region of hadron gas and quark-gluon plasma (QGP). The presence of QGP gives hadrons larger widths than they would have in a pure hadron gas. We find ...
    • J/psi absorption by nucleons in the meson-exchange model 
      Oh, Yongseok; Liu, Wei; Ko, Che Ming. (American Physical Society, 2007)
      We reinvestigate the J/Psi dissociation processes induced by the reactions with nucleons, J/Psi + N -> D-(*) + Lambda(c), in the meson- exchange model. Main constraints used in this work are vector- meson dominance and ...
    • 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 ...
