Description
In this talk, I will summarize our (PNDME collaboration [1]) lattice QCD calculations of the flavor diagonal charges of the nucleon using ensembles generated by the MILC collaborations. These include both connected and disconnected contributions, and the full nonperturbative calculation of the renormalization constants in the 2+1 flavor theory is used to present the final results in the $\overline{MS}$ scheme at 2GeV. In addition, I will present preliminary results on nucleon isovector form factors from two new physical pion mass ensembles representing a sixfold increase in statistics, improved quark mass quark tuning, and a larger range of momentum-transfers that extends up to $Q^2\sim 1GeV^2$. These calculations were done using computing resources at OLCF and NERSC.
