Description
We calculate the dilepton spectrum at the mass range of the low-lying charmonium states in $\bar p$, p and $\pi$ 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 charmonium contribution to the dilepton spectrum and show that for $\Psi$(3686) production there is a good chance to observe its in-medium modification with good resolution detectors. We,furthermore, show that by studying the excitation function of the charmonium state J/$\Psi$ in $\bar p$A collisions we may study the high momentum tail of the protons inside the nuclei.
