Coulomb corrections to pi-pi scattering
Norman Christ, Xu Feng, Joseph Karpie +1
The relationship between finite volume multi-hadron energy levels and matrix elements and two particle scattering phase shifts and decays is well known, but the inclusion of long r…
scattering, QED and finite-volume quantization
Norman Christ, Xu Feng, Joseph Karpie +1
Using the Coulomb gauge formulation of QED we present a lattice QCD procedure to calculate the scattering phase shift including the effects of the Coulomb potential which…
The transversity parton distribution function of the nucleon using the pseudo-distribution approach
Colin Egerer, Christos Kallidonis, Joseph Karpie +8
We present a determination of the non-singlet transversity parton distribution function (PDF) of the nucleon, normalized with respect to the tensor charge at GeV from l…
Unpolarized gluon distribution in the nucleon from lattice quantum chromodynamics
Tanjib Khan, Raza Sabbir Sufian, Joseph Karpie +9
In this study, we present a determination of the unpolarized gluon Ioffe-time distribution in the nucleon from a first principles lattice quantum chromodynamics calculation. We car…
The Continuum and Leading Twist Limits of Parton Distribution Functions in Lattice QCD
Joseph Karpie, Kostas Orginos, Anatoly Radyushkin +1
In this study, we present continuum limit results for the unpolarized parton distribution function of the nucleon computed in lattice QCD. This study is the first continuum limit u…
