Charmonium production in $\bar{p}$-induced reactions on nuclei

Abstract

The production of charmonia in the antiproton-nucleus reactions at $p_{\mathrm{lab}}=3-10$ GeV/c is studied within the Glauber model and the generalized eikonal approximation. The main reaction channel is charmonium formation in an antiproton-proton collision. The target mass dependence of the charmonium transparency ratio allows to determine the charmonium-nucleon cross section. The polarization effects in the production of ${\chi }_{c2}$ states are evaluated.
