Quarkonium-hadron interactions in QCD
Yongseok Oh, Sungsik Kim, Su Houng Lee
The leading order non-relativistic QCD result for the quarkonium-hadron interaction cross section is derived by using the QCD factorization formula combined with the Bethe-Salpeter…

QCD sum rules for J/psi in the nuclear medium: calculation of the Wilson coefficients of gluon operators up to dimension 6
Sungsik Kim, Su Houng Lee
We calculate the Wilson coefficients of all dimension 6 gluon operators with non zero spin in the correlation function between two heavy vector currents. For the twist-4 part, we f…

J/psi and eta_c in the nuclear medium: QCD sum rule approach
Frank Klingl, Sungsik Kim, Su Houng Lee +2
We investigate the masses of the lowest c\bar{c} states, the J/psi and eta_c, in nuclear matter using QCD sum rules. Up to dimension four, the differences between the operator prod…
