Description
We present the results of the nucleon axial-vector charge based on PACS10 gauge ensembles. These ensembles are generated by PACS Collaboration using stout-smeared O(a) improved Wilson-clover quark action and Iwasaki gauge action, and they are characterized by the spatial extent of 10 fm and three lattice spacings 0.09 fm, 0.06 fm and 0.04 fm. In particular, the latest update at 0.04 fm is provided. The PCAC mass is also evaluated from the nucleon three-point functions to verify the axial Ward-Takahashi identity.
