In-medium decay widths of hidden and open charm vector mesons in a field theoretic model for composite hadrons

Amruta Mishra, S. P. Misra, W. Greiner

We calculate the decay widths of the charmonium states, $J/\psi$, $\psi (3686)$ and $\psi (3770)$, to $D\bar{D}$ pairs, as well as the decay width of $D^{\ast }\to D\pi$, in isospin asymmetri…
