Abstract:
We study the perspectives of resonant charmonium production in (p) over bar + A reactions within the Multiple Scattering Monte Carlo (MSMC) approach. IvVe calculate the production of the resonances Psi(2S) and Psi(3770) on various nuclei, their propagation and decay to-dileptons and D + (D) over bar in the medium and vacuum, respectively, employing pararnetrizations for the D, (D) over bar self-energies taken from QCD sum rule studies. The elastic and inelastic interactions of the charmonia and open-charm mesons in the medium are taken into account, too. It is found that the D, (D) over bar invariant-mass spectra from light and heavy nuclei are not sufficiently sensitive to the in-medium properties of the Psi(2S) and Psi(3770). However, a "suppression" of-low-mass dileptons from the Psi(3770) might be seen experimentally as well as a small broadening of the Psi(2S) dilepton spectra.
