The cross sections for $J/\ensuremath{\psi}$ absorption by $\ensuremath{\pi}$ and $\ensuremath{\rho}$ 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 …
