Charmonium production in p-induced reactions on nuclei

Abstract

The production of charmonia in the antiproton-nucleus reactions at p 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 c2 states are evaluated.
