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…

A simple non-parametric reconstruction of parton distributions from limited Fourier information

Hervé Dutrieux, Joseph Karpie, Kostas Orginos +1

Some calculations of parton distributions from first principles only give access to a limited range of Fourier modes of the function to reconstruct. We present a physically motivat…

Proton internal pressure from deeply virtual Compton scattering on collider kinematics

Hervé Dutrieux, Thibaud Meisgny, Cédric Mezrag +1

The unique experimental connection to the QCD energy-momentum tensor offered by generalised parton distributions has been strongly highlighted in the past few years with attempts t…
