Description
In this talk, I will report some recent progress in extracting the gluonic gravitational form factors (GFFs) from near threshold heavy quarkonium productions. Particularly, I will discuss the effect of the next-to-leading order (NLO) corrections on the extraction of the GFFs, where the singlet quark contribution will also emerge. With the NLO corrections, I will remark on the theoretical uncertainties of the extraction, and also comment on the possibility to extend to other exclusive processes.
