Isovector and Isoscalar charges of the nucleon
We present results for the isovector and isoscalar charges of the nucleon. The 2+1+1-flavor calculations were done using MILC HISQ ensembles with three lattice spacings a=0.12, 0.09, 0.06 fm and three pion masses approximately 310, 220, 130 MeV. The 2+1-flavor clover calculations were done on four ensembles with approximately 300 and 190 MeV pion masses.
