Near-threshold quarkonium photo- and electro-production and the QCD energy momentum tensor
ORAL
Abstract
I will discuss recent theory progress in understanding near-threshold photo- and lepto-production of heavy quarkonium in electron-proton scattering.
This is a unique process which allows one to experimentally access the gluon gravitational form factors of the nucleon, in particular the so-called D-term and the gluon condensate related to the origin of nucleon mass.
