Excited-state effects in nucleon structure on the lattice using hybrid interpolators
Jeremy R. Green, Michael Engelhardt, Nesreen Hasan +5
It would be very useful to find a way of reducing excited-state effects in lattice QCD calculations of nucleon structure that has a low computational cost. We explore the use of hy…
Nucleon axial, scalar, and tensor charges using lattice QCD at the physical pion mass
Nesreen Hasan, Jeremy Green, Stefan Meinel +5
We report on lattice QCD calculations of the nucleon isovector axial, scalar, and tensor charges. Our calculations are performed on two 2+1-flavor ensembles generated using a 2-HEX…
Quark orbital angular momentum in the proton evaluated using a direct derivative method
M. Engelhardt, J. Green, N. Hasan +5
Quark orbital angular momentum (OAM) in the proton can be calculated directly given a Wigner function encoding the simultaneous distribution of quark transverse positions and momen…
