Moments of parton distributions functions of the pion from lattice QCD using gradient flow
Anthony Francis, Patrick Fritzsch, Rohith Karur +7
We present a nonperturbative determination of the pion valence parton distribution function (PDF) moment ratios …
Gaussian Processes for Inferring Parton Distributions
Yamil Cahuana Medrano, Hervé Dutrieux, Joseph Karpie +2
The extraction of parton distribution functions (PDFs) from experimental or lattice QCD data is an ill-posed inverse problem, where regularization strongly impacts both systematic…
Gradient flow for parton distribution functions: first application to the pion
Anthony Francis, Patrick Fritzsch, Robert V. Harlander +9
Parton distribution functions (PDFs) are central to precision QCD phenomenology. Their Mellin moments can be computed on the lattice, but direct determinations using local operator…
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…
