Inclusive diffractive heavy quarkonium photoproduction including quark subprocesses

Jiayu Wu, Yanbing Cai, Wenchang Xiang

The inclusive $J/\Psi$, $\Psi (2S)$ and ${\rm Y}(1S)$ direct and resolved photoproduction are investigated by including the quark subprocesses in the framework of non-relativistic quantum chrom…
