J/ψ -kaon cross section in meson exchange model
Abstract
We calculate the cross section for the dissociation of J/ψ 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/ψ -kaon cross section was found to be 1.0 1.6 mb for 4.1⩽√(s)⩽5 GeV .
