$J/\psi$-kaon cross section in meson exchange model

Abstract

We calculate the cross section for the dissociation of $J/\psi$ by kaons within the framework of a meson exchange model including anomalous parity interactions. Off-shell effects at the vertices were handled with QCD sum rule estimates for the running coupling constants. The total $J/\psi$-kaon cross section was found to be $1.0\sim 1.6$ mb for $4.1\leq\sqrt{s}\leq5 \GeV$.
