Nucleon form factors with Nf=2+1 domain wall fermions

Presenter: Takeshi Yamazaki — Univ. of Conn.

We present our results of iso-vector vector and axial-vector nucleon form factors using Nf=2+1 dynamical domain wall fermions (DWF) and Iwasaki gauge action at β = 2.13 corresponding to a−1 ≈ 1.6 GeV. We investigate the pion mass dependence of the form factors with four pion masses, mπ∼ 310, 390, 520, 690 MeV. We discuss the finite volume effect in the axial charge gA/gV and the form factors. The results are compared with the Nf=2 dynamical DWF results and experiments.
