Neural-network analysis of Parton Distribution Functions from Ioffe-time pseudodistributions

High Energy Physics - Phenomenology 2021-03-17 v2 High Energy Physics - Lattice

Abstract

We extract two nonsinglet nucleon Parton Distribution Functions from lattice QCD data for reduced Ioffe-time pseudodistributions. We perform such analysis within the NNPDF framework, considering data coming from different lattice ensembles and discussing in detail the treatment of the different source of systematics involved in the fit. We introduce a recipe for taking care of systematics and use it to perform our extraction of light-cone PDFs.
