Interactions of charmed mesons with nucleons in the $\bar{p}d$ reaction

Abstract

We study the possibility to measure the elastic $\Phi N$ ($\Phi \equiv J/\psi ,\psi (2S),\psi (3770),{\chi }_{2c}$) scattering cross section in the reaction $\bar{p}+d\to \Phi +n_{sp}$ and the elastic $D(\bar{D})N$ scattering cross section in the reaction $\bar{p}+d\to D^{-}{D}^0{p}_{sp}$. Our studies indicate that the elastic scattering cross sections can be determined for $\Phi$ momenta about 4-6 GeV/c and $D/\bar{D}$ momenta 2 -- 5 GeV/c by selecting events with $p_t\ge 0.4$ GeV/c for $\Phi$'s and $p_t(p_{sp})\ge$ 0.5 GeV/c for $D/\bar{D}$-meson production.
