Charmonium Excitation functions in $\bar{p}$A Collisions

Abstract

We study the excitation function of the low-lying charmonium state: $\Psi$(3686) in $\bar{p}$ Au collisions taking into account their in-medium propagation. The time evolution of the spectral functions of the charmonium state is studied with a BUU type transport model. We calculated the excitation function of $\Psi$(3686) production and show that it is strongly effected by the medium. The energy regime will be available for the PANDA experiment.
