Nucleon scalar and tensor charges from lattice QCD with light Wilson quarks

Nucleon scalar and tensor charges from lattice QCD with light Wilson quarks

We present 2+1 flavor lattice QCD calculations of the nucleon scalar and tensor charges. Using the BMW clover-improved Wilson action with pion masses between 149 and 356 MeV and three source-sink separations between 0.9 and 1.4 fm, we achieve good control over excited-state contamination and extrapo...
