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…

Reconstructing the full kinematic dependence of GPDs from pseudo-distributions

Hervé Dutrieux, Robert G. Edwards, Joe Karpie +7

We propose a reconstruction of the full dependence of unpolarized isovector proton generalized parton distributions (GPDs) and from lattice QCD data…

Accessing the Gluon Momentum Fraction of Nucleons through the Gradient Flow

Robert Edwards, Joe Karpie, Lorenzo Maio +5

We calculate the gluon momentum fraction of the nucleon using lattice quantum chromodynamics (QCD), with a nonperturbative renormalization technique based on the gradient flow. The…

Comment on "LaMET's Asymptotic Extrapolation vs. Inverse Problem"

Hervé Dutrieux, Joe Karpie, Christopher J. Monahan +4

In arXiv:2504.17706 {Dutrieux:2025jed} we criticized the excessive model-dependence introduced by rigid few-parameter fits to extrapolate lattice data in the large momentum effecti…

Window observables for benchmarking parton distribution functions

Joe Karpie, Christopher J. Monahan, Kostas Orginos +1

Global analysis of collider and fixed-target experimental data and calculations from lattice quantum chromodynamics (QCD) are used to gain complementary information on the structur…

Inverse problem in the LaMET framework

Hervé Dutrieux, Joe Karpie, Christopher J. Monahan +4

One proposal to compute parton distributions from first principles is the large momentum effective theory (LaMET), which requires the Fourier transform of matrix elements computed…

Evolution of Parton Distribution Functions in the Short-Distance Factorization Scheme

H. Dutrieux, J. Karpie, C. Monahan +2

Lattice QCD offers the possibility of computing parton distributions from first principles, although not in the usual factorization scheme. We study in this paper t…

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…
