    "abstract": "In this work we study the energy dependence of the $J/\\psi-K^*$ dissociation\ncross section, using a meson exchange model based on effective hadronic\nLagrangian that includes couplings between pseudoscalar and vector mesons. We\nalso consider anomalous parity terms.\n  Off-shell effects at the vertices were handled with QCD sum rule estimates\nfor the running coupling constants, and we compare the results with and without\nform factors. We also study the $J/\\psi-\\rho$ cross section with form factors.\nThe total $J/\\psi-K^*$ cross section was found to be $1.6 \\sim1.9$ mb for\n$4.2\\leq\\sqrt{s}\\leq5~\\GeV$.",
