J/\Psi production in \pi N collisions

Abstract

We calculate the total cross section for $\pi N\to J/\Psi N$ based on $\rho$-meson exchange. On the basis of this calculation we predict a maximal reaction rate arising from the OZI-violating $J/\Psi \leftrightarrow \rho \pi$ vertex in tree-level. Our estimate for the maximum reaction rate is still one order of magnitude smaller than the existing predictions which were based on the other OZI-violating mechanisms.
