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/\ensuremathψN and \ensuremathη_cN scattering amplitudes and cross sections into 46 final channels, including final states composed of various combinations of D,D^*,\ensuremathΣ_c, and \ensuremathΛ_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 cc production to the open-charm final states observed at the BNL Relativistic Heavy Ion Collider (RHIC) through the characteristic flavor ratios of certain channels. These results are also of interest in relation to possible charmonium-nucleon bound states.
