Nucleon axial and tensor charges with dynamical overlap quarks

Understand

We report on our calculation of the nucleon axial and tensor charges in 2+1-flavor QCD with dynamical overlap quarks.

• Gauge ensembles are generated at a single lattice spacing 0.12 fm and at a strange quark mass close to its physical value.
• We employ the all-mode-averaging technique to calculate the relevant nucleon correlation functions, and the disconnected quark loop is efficiently calculated by using the all-to-all quark propagator.
• We present our preliminary results for the isoscalar and isovector charges obtained at pion masses $m_\pi$ = 450 and 540 MeV.
