Description

We present a theoretical update on the analysis of threshold heavy quarkonium e.g., $J/\psi$, production measurements. It has been shown that the such processes can be factorized with gluon generalized parton distributions (GPDs) which allow us to further connect to the gluonic gravitational form factors (GFFs) in the large $\xi$ limit. We will discuss the GPDs at large skewness with more details and present a more careful analysis.
