Description
Results from ongoing calculations of the "nucleon charges" by the PNDME and NME collaboration are presented. These are based on preliminary data from O(7000) configurations on two physical pion mass ensembles with 2+1+1-flavor ensembles generated by the MILC collaboration at lattice spacing $a=0.087$ and $a=0.0576$ fm and 11 NME ensembles with 2+1-flavor clover action generated by JLab/W\&M/LANL/MIT/Marseille collaborations. Control of excited-state contamination is discussed in the extraction of the axial, scalar, and tensor charges.
