Nucleon isovector form factors from physical-mass 2+1-flavor dynamical domain-wall QCD

Abstract

The current status is reported of joint lattice numerical calculations by LHP and RBC collaborations of isovector nucleon form factors using 2+1-flavor physical-mass domain-wall fermions ensemble at a lattice cutoff 𝑎 −1 of 1.730(4) GeV and spatial volume of (𝐿𝑎 = 5.471(13)fm) 3 generated jointly by RBC and UKQCD collaborations.
