Charm production in antiproton-nucleus collisions at the $J/\psi$ and the ${\psi }^{\prime }$ thresholds

Abstract

We discuss the production of charmonium states in antiproton-nucleus collisions at the ${\psi }^{\prime }$ threshold. It is explained that measurements in $\bar{p}A$ collisions will allow to get new information about the strengths of the inelastic $J/\psi N,{\psi }^{\prime }N$ interaction, on the production of ${\Lambda }_c$ and $\bar{D}$ in charmonium-nucleon interactions and for the first time about nondiagonal transitions ${\psi }^{\prime }N\to J/\psi N$. The inelastic $J/\psi$-nucleon cross section is extracted from the comparison of hadron-nucleus collisions with hadron-nucleon collisions. We extract the total $J/\psi$ nucleon cross section from photon-nucleon collisions by accounting for the color transparency phenomenon within the frame of the GVDM (Generalized Vector meson Dominance Model). We evaluate also within the GVDM the inelastic ${\psi }^{\prime }$-nucleon cross section as well as the cross section for the nondiagonal transitions. Predictions for the ratio of $J/\psi$ to ${\psi }^{\prime }$ yields in antiproton-nucleus scatterings close to the threshold of ${\psi }^{\prime }$ production for different nuclear targets are presented.
