We calculate the dilepton spectrum at the mass range of the low-lying charmo- nium states in 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 charmonium contribu- tion to the dilepton spectrum and show that for (3686) production there is a good chance to observe its in-medium modification with good resolution de- tectors. We, furthermore, show that the excitation function of the charmonium state (3686) does not show a jump at production threshold in p Au collisions as it does in elementary pp collisions due to the high momentum tail of the nucleons.
