Gluon GPDs and exclusive photoproduction of quarkonium in forward region
Abstract Forward photoproduction of $$J/\psi $$ J/ψ can be used to extract generalized parton distributions (GPDs) of gluons. We analyze the process at twist-3 level and study relevant classifications of twist-3 gluon GPDs. At leading power or twist-2 level the produced $$J/\psi $$ J/ψ is transverse...
