Nucleon axial charge from quenched lattice QCD with domain wall fermions and improved gauge action

Shoichi Sasaki, Tom Blum, Shigemi Ohta +1

In our previous DWF calculation with the Wilson gauge action at $\beta =6.0$ ($a^{-1}\simeq$ 1.9 GeV) on a $16^3\times 32\times 16$ lattice, we found that $\Ga$ had a fairly strong de…
