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

Luigi Del Debbio, Tommaso Giani, Joseph Karpie +3

We extract two nonsinglet nucleon Parton Distribution Functions from lattice QCD data for reduced Ioffe-time pseudodistributions. We perform such analysis within the NNPDF framewor…

Parton Distribution Functions from Ioffe Time Pseudodistributions from Lattice Calculations: Approaching the Physical Point

Bálint Joó, Joseph Karpie, Kostas Orginos +3

We present results for the unpolarized parton distribution function of the nucleon computed in lattice QCD at the physical pion mass. This is the first study of its kind employing…

Pion Valence Structure from Ioffe Time Pseudo-Distributions

Bálint Joó, Joseph Karpie, Kostas Orginos +4

We present a calculation of the pion valence quark distribution extracted using the formalism of reduced Ioffe time pseudo-distributions or more commonly known as pseudo-PDFs. Our…

Parton Distribution Functions from Ioffe time pseudo-distributions

Bálint Joó, Joseph Karpie, Kostas Orginos +3

In this paper, we present a detailed study of the unpolarized nucleon parton distribution function (PDF) employing the approach of parton pseudo-distribution functions. We perform…

Reconstructing parton distribution functions from Ioffe time data: from Bayesian methods to Neural Networks

Joseph Karpie, Kostas Orginos, Alexander Rothkopf +1

The computation of the parton distribution functions (PDF) or distribution amplitudes (DA) of hadrons from first principles lattice QCD constitutes a central open problem. In this…

Moments of Ioffe time parton distribution functions from non-local matrix elements

Joseph Karpie, Kostas Orginos, Savvas Zafeiropoulos

We examine the relation of moments of parton distribution functions to matrix elements of non-local operators computed in lattice quantum chromodynamics. We argue that after the co…
