Lattice QCD Calculations of Parton Physics
Martha Constantinou, Luigi Del Debbio, Xiangdong Ji +12
In this document, we summarize the status and challenges of calculating parton physics in lattice QCD for the US Particle Physics Community Planning Exercise (a.k.a. "Snowmass"). W…
Pion valence quark distribution from current-current correlation in lattice QCD
Raza Sabbir Sufian, Colin Egerer, Joseph Karpie +6
We extract the pion valence quark distribution from lattice QCD (LQCD) calculated matrix elements of spacelike correlations of one vector and one axial vector curr…
Pion Valence Quark Distribution from Matrix Element Calculated in Lattice QCD
Raza Sabbir Sufian, Joseph Karpie, Colin Egerer +3
We present the first exploratory lattice QCD calculation of the pion valence quark distribution extracted from spatially separated current-current correlations in coordinate space.…
Matching issue in quasi parton distribution approach
Tomomi Ishikawa, Yan-Qing Ma, Jian-Wei Qiu +1
In recent years, the quasi parton distribution has been introduced for extracting the parton distribution functions from lattice QCD simulations. The quasi and standard distributio…
Practical quasi parton distribution functions
Tomomi Ishikawa, Yan-Qing Ma, Jian-Wei Qiu +1
A completely new strategy to calculate parton distribution functions on the lattice has recently been proposed. In this method, lattice calculable observables, called quasi distrib…
