The Continuum and Leading Twist Limits of Parton Distribution Functions in Lattice QCD

Understand

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 using the pseudo-PDF approach with Short Distance Factorization for factorizing lattice QCD calculable matrix elements.
• Our findings are also compared with the pertinent phenomenological determinations.
• Inter alia, we are employing the summation Generalized Eigenvalue Problem (sGEVP) technique in order to optimize our control over the excited state contamination which can be one of the most serious systematic errors in this type of calculations.
