Description

The energy–momentum tensor (EMT) provides a fundamental, gauge-invariant description of the distribution of energy, momentum, and internal forces within hadrons. Its matrix elements define the gravitational form factors (GFFs), which encode key aspects of nucleon structure, including mass decomposition, spatial distributions of pressure and shear forces, and the angular momentum carried by quarks and gluons. In this talk, I will present recent phenomenological results of gluonic GFFs and their application to the near-threshold photoproduction of $J/\psi$, with predictions relevant to the $J/\psi-007$ and GlueX experiments at Jefferson Lab and their implications at EIC within the generalized parton distribution framework.
