Nucleon scalar and tensor couplings from lattice QCD at the physical points

Nucleon scalar and tensor couplings from lattice QCD at the physical points

We present results for the axial, scalar and tensor isovector-couplings (gA, gS and gT) of the nucleon obtained from 2+1 flavor QCD with the physical light quark masses (Mπ = 135 MeV). Our calculations are performed at a single lattice spacing of 0.085 fm, but with two large volumes of (10.9 fm)4 an...
