Distillation at High-Momentum
Colin Egerer, Robert G. Edwards, Kostas Orginos +1
Extraction of hadronic observables at finite-momenta from Lattice QCD (LQCD) is constrained by the well-known signal-to-noise problems afflicting all such LQCD calculations. Tradit…
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.…
Controlling Excited-State Contributions with Distillation in Lattice QCD Calculations of Nucleon Isovector Charges , ,
Colin Egerer, David Richards, Frank Winter
We investigate the application of the distillation smearing approach, and the use of the variational method with an extended basis of operators facilitated by this approach, on the…
