Lattice QCD Calculation of Nucleon Structure

A program to study nucleon structure from lattice Quantum Chromodynamics (QCD) with chiral fermions at the physical pion mass is proposed. We would like to undertake the task of computing quark propagators of the overlap fermion and the gauge field tensor for the quark and glue observables in the nucleon on an ensemble of dynamical fermion gauge configurations with the 2 + 1-flavor domain-wall fermion (DWF) action on four lattice spacings and three volumes that include two large ones (48 cubed x 96 and 64 cubed x 128) at the physical pion mass and a spatial size of 5.4 - 5.5 fm. Combining results from the smaller lattices and these large lattices, we will perform large volume and continuum extrapolations for observables at the physical pion mass to be compared with existing experiments and to make predictions for those which will be measured in future experiments and phenomenology.
