Description
The light-cone definition of Parton Distribution Functions (PDFs) does not allow for a direct ab initio determination employing methods of Lattice QCD simulations that naturally take place in Euclidean spacetime. In this presentation we focus on pseudo-PDFs where the starting point is the equal time hadronic matrix element with the quark and anti-quark fields separated by a finite distance. We present lattice results for the case of the nucleon and the pion addressing among others the physical point and continuum extrapolations. Then we will show, how an improved smearing method (distillation) opens the gates for high precision results for the nucleon quark (un)-polarized distributions, gluon (un)-polarized distributions.
Finally we will discuss the interplay and synergies between lattice methods and phenomenological global analyses. Closing, we plan to show results for the nucleon Generalized Parton Distributions and discuss nucleon tomography applications for the EIC.
