Exclusive $J/\ddot{I}ˆ$ production in proton-proton collisions adopting GPD approach

Ya-Ping Xie, S. V. Goloskokov

Exclusive $J/\ddot{I}ˆ$ production is investigated in proton-proton collisions employing GPD approach with GK model. Three sets gluon density are used to calculate exclusive $J/\ddot{I}ˆ$ produc…
