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 dat…
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…
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…
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…
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…
