The energy momentum tensor (EMT) and its form factors have been one of the major theme of hadron physics in the past decades. In this talk I will discuss how one can get an experimental access to them through deeply virtual Compton scattering, and why this kind of process, measured at the JLab and the EIC is not enough to provide constraints on the gluon sector.
Understanding the internal structure of hadrons requires a detailed study of parton distributions. In particular, distributions in the transverse directions—Transverse Momentum Dependent distributions (TMDs) and Generalized Parton Distributions (GPDs)—provide essential insights. Lattice QCD and Large Momentum Effective Theory (LaMET) offer ab initio calculations of TMDs and GPDs. In our...
In recent years, there has been a growing interest in the possibility of extracting parton distributions of QCD from Lattice simulations. Since it is not possible to extract the light-cone distributions via Lattice QCD, they are extracted in the Euclidean region $z_E^2 = - z^2 > 0$, and then matched to the light-cone one, through the use of perturbative math kernels. In the case of heavy-quark...
