Nucleon-sigma terms at with a variational analysis from lattice QCD
Lorenzo Barca, Gunnar Bali, Sara Collins +1
Nucleon sigma terms are important for the decomposition of the nucleon mass and for searches for new physics beyond the Standard Model involving scalar interactions. A persistent t…
Third moments of nucleon unpolarized, polarized, and transversity parton distribution functions from physical-point lattice QCD
Emilio Taggi, Michael Engelhardt, Jeremy R. Green +6
Using forward matrix elements of local leading-twist operators, we present a determination of the isovector third Mellin moments of nucleon unpolarized, polari…
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…
Moments of Nucleon Unpolarized, Polarized, and Transversity Parton Distribution Functions from Lattice QCD at the Physical Point
Marcel Rodekamp, Michael Engelhardt, Jeremy R. Green +6
The second Mellin moments of the nucleon's unpolarized, polarized, and transversity parton distribution functions (PDFs) are computed. Two lattice QCD ensembles…
Moments of Parton Distributions Functions from Lattice QCD at the Physical Point
Marcel Rodekamp, Michael Engelhardt, Jeremy R. Green +5
We present a Lattice QCD calculation of the second Mellin moments of the nucleon axial, vector and tensor parton distribution functions (PDFs). The calculation is performed at the…
