Description
In this poster, I present preliminary results from the Fermilab Lattice and MILC collaborations on the nucleon axial charge and nucleon axial and vector form factors with the HISQ action for both valence and 2+1+1 sea quarks. For the nucleon axial charge, we compute correlators across four physical mass ensembles with approximate lattice spacings of 0.15, 0.12, 0.09, and 0.06 fm, and perform continuum extrapolation; for the nucleon form factors, we compute correlators on a 300 MeV pion-mass ensemble with the approximate lattice spacing of 0.12 fm and demonstrate the method to extract nucleon form factors with staggered action.
