Charmonium-Nucleon Dissociation Cross Sections in the Quark Model

Abstract

Charmonium dissociation cross sections due to flavor-exchange charmonium-baryon scattering are computed in the constituent quark model. We present results for inelastic $J/\psi N$ and ${\eta }_{c}N$ scattering amplitudes and cross sections into 46 final channels, including final states composed of various combinations of $D$, $D^{\ast }$, ${\Sigma }_c$, and ${\Lambda }_c$. These results are relevant to experimental searches for the deconfined phase of quark matter, and may be useful in identifying the contribution of initial $c\bar{c}$ production to the open-charm final states observed at RHIC through the characteristic flavor ratios of certain channels. These results are also of interest to possible charmonium-nucleon bound states.
