    • Charmonium mass in nuclear matter 

      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 ...
    • Model for J/psi absorption in hadronic matter 

      Lin, ZW; Ko, Che Ming. (American Physical Society, 2000)
      The cross sections for J/psi absorption by pi and rho mesons are studied in a meson-exchange model that includes not only pseudoscalar-pseudoscalar-vector-meson couplings but also three-vector-meson and four-point couplings. ...
