Title: Stochastic method with low mode substitution for nucleon isovector matrix elements

Abstract

We introduce a stochastic method with low-mode substitution to evaluate the connected three-point functions. The isovector matrix elements of the nucleon for the axial-vector coupling g$$^{3}_{A}$$ , scalar couplings g $$^{3}_{S}$$ and the quark momentum fraction $$\langle$$ x $$\rangle$$ u-d are calculated with overlap fermion on 2 + 1 flavor domain-wall configurations on a 24 3 × 64 lattice at m π = 330 MeV with lattice spacing a = 0.114 fm .
