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…

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…

Non-local Nucleon Matrix Elements in the Rest Frame
Joe Karpie, Christopher Monahan, Anatoly Radyushkin
Extracting parton structure from lattice quantum chromodynamics (QCD) calculations requires studying the coordinate scale dependence of the matrix elements of bilocal operato…
