Nucleon structure from 2+1-flavor dynamical Domain-Wall Fermion ensembles

I will discuss lattice-QCD numerical calculations of nucleon structures using 2+1-flavor dynamical domain-wall fermion (DWF) ensembles jointly generated by RIKEN-BNL-Columbia (RBC) and UKQCD collaborations. 
In these ensembles strange-quark mass is set essentially at its physical value and degenerate up- and down-quark mass is set as light as practical, down to pion mass of about 172 MeV.  We are finishing our
analysis for iso vector observables such as vector- and axialvector-current form factors, transversity, scalar charge, and quark momentum and helicity fractions.  And we are resuming calculations at physical
pion mass this summer.
