DOI: 10.1007/jhep09(2020)021
Abstract: We review recent theoretical developments concerning the definition and the renormalization of equal-time correlators that can be computed on the lattice and related to Parton Distribution Functions (PDFs) through a factorization formula. We show how… read more here.
