Femtoscale imaging of the proton with Ioffe-time distributions
Robert G. Edwards, Joe Karpie, Christopher Monahan +5
Mapping how strongly interacting constituents are distributed within protons is a key goal of nuclear physics and a major direction of the future Electron Ion Collider program. We…
Gluon helicity from global analysis of experimental data and lattice QCD Ioffe time distributions
J. Karpie, R. M. Whitehill, W. Melnitchouk +6
We perform a new global analysis of spin-dependent parton distribution functions with the inclusion of Ioffe time pseudo-distributions computed in lattice QCD (LQCD), which are dir…
Complementarity of experimental and lattice QCD data on pion parton distributions
P. C. Barry, C. Egerer, J. Karpie +8
We extract pion parton distribution functions (PDFs) in a Monte Carlo global QCD analysis of experimental data together with reduced Ioffe time pseudo-distributions and matrix elem…
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…
Lattice QCD exploration of pseudo-PDFs
Kostas Orginos, Anatoly Radyushkin, Joseph Karpie +1
We demonstrate a new method of extracting parton distributions from lattice calculations. The starting idea is to treat the generic equal-time matrix element ${\cal M} (Pz_3, z_3^2…
