J/psi absorption by pi and rho mesons in a meson exchange model with anomalous parity interactions

Abstract

We reanalyze the dissociation process of the $J/\psi$ by $\pi$ and $\rho$ mesons into $D+\bar{D}$, $D^{\ast }+\bar{D}$, $D+{\bar{D}}^{\ast }$, and $D^{\ast }+{\bar{D}}^{\ast }$ within a meson exchange model. In addition to the dissociation mechanisms considered in the literature, we consider anomalous parity interactions, whose couplings are constrained by heavy quark spin symmetry and phenomenology. This opens new dissociation channels and adds new diagrams in the previously considered processes. Compared to the previous results, we find that these new additions have only a minor effect on the $\rho +J/\psi$ total inelastic cross section, but reduce the one for $\pi +J/\psi$ by about 50 % near the threshold.
