dc.description.abstractThe 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. We find that they are much larger than in a previous study where only pseudoscalar-pseudoscalar-vector-meson couplings were considered. Including form factors at interaction vertices, the J/psi absorption cross sections sigma(pi psi) and sigma(rho psi) are found to have values on the order of 7 mb and 3 mb, respectively. Their thermal averages in hadronic matter at temperature T = 150 MeV are, respectively, about 1 mb and 2 mb.en
