[en] We present results for nucleon iso-vector charges from dynamical lattice QCD with domain-wall quarks. Simulations are performed on the 2 + 1 flavor gauge configurations generated by the RBC and UKQCD Collaborations at two different lattice spacings of a = 0.114(2) and 0.086(2) fm with a range of pion masses down to Mπ ≈ 290 MeV. We computed nucleon three-point correlation functions in the vector, axial-vector, scalar, and tensor channels. The bare local currents are renormalized non-perturbatively in the regularization independent momentum (RI/SMOM) scheme, while the renormalized matrix elements are evaluated in the MS-bar scheme through matching between the renormalized operators and the perturbative MS-bar scheme at the renormalization scale of 2 GeV. We then evaluate the renormalized iso-vector charges of the nucleon for the axial, scalar and tensor channels. (author)
