Quark orbital angular momentum in the proton from a twist-3 generalized parton distribution
M. Engelhardt, N. Hasan, S. Krieg +6
Quark orbital angular momentum in the proton is evaluated via a Lattice QCD calculation of the second Mellin moment of the twist-3 generalized parton distribution $\widetilde{E}_{2…
Transverse momentum-dependent parton distributions for longitudinally polarized nucleons from domain wall fermion calculations at the physical pion mass
M. Engelhardt, N. Hasan, T. Izubuchi +7
Previous Lattice QCD calculations of nucleon transverse momentum-dependent parton distributions (TMDs) focused on the case of transversely polarized nucleons, and thus did not enco…
Quark spin-orbit correlations in the proton
M. Engelhardt, J. R. Green, N. Hasan +10
Generalized transverse momentum-dependent parton distributions (GTMDs) provide a comprehensive framework for imaging the internal structure of the proton. In particular, by encodin…
From Ji to Jaffe-Manohar orbital angular momentum in Lattice QCD using a direct derivative method
M. Engelhardt, J. R. Green, N. Hasan +5
A Lattice QCD approach to quark orbital angular momentum in the proton based on generalized transverse momentum-dependent parton distributions (GTMDs) is enhanced methodologically…
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…
