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…
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…
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…
