Nucleon mass and isovector couplings in 2+1-flavor dynamical domain-wall lattice QCD near physical mass

We report nucleon mass, isovector vector and axial-vector charges, and tensor and scalar couplings, calculated using two recent 2+1-flavor dynamical domain-wall fermions lattice-QCD ensembles generated jointly by the RIKEN-BNL-Columbia and UKQCD collaborations. These ensembles were generated with Iwasaki \times dislocation-suppressing-determinant-ratio gauge action at inverse lattice spacing of 1.378(7) GeV and... Show more
