$J/\ddot{I}ˆ$ photoproduction and polarization in $e+p$ collisions in the improved color evaporation model

Vincent Cheung, Ramona Vogt

We calculate the production and polarization of direct $J/\ddot{I}ˆ$ in the improved color evaporation model in $e+p$ photoproduction. We present the production as functions of transverse…
