Description
The formalism of short-distance factorization connects light-cone correlators with spacelike ones. The later can be computed in Euclidean spacetime, common to many functional approaches to field theory. The former are central objects in the study of hadron structure, entering the definition of parton distributions. In this work we review the application of this formalism, conveyed through the pseudo-distribution approach, to the extraction of parton distribution functions from lattice QCD. As an illustration, we consider the case of a heavy pseudoscalar meson: the $\eta_{c}$. We will present the first model independent extraction of the parton distribution of valence quarks within an $\eta_{c}$ meson.
