J/Ψproduction in πN collisions
Abstract
Description
We calculate the total cross section for $πN \to J/ΨN$ based on $ρ$-meson exchange. On the basis of this calculation we predict a maximal reaction rate arising from the OZI-violating $J/Ψ{\leftrightarrow}ρπ$ 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.
