Polarized structure functions from the lattice

High Energy Physics - Lattice 2007-05-23 v1

Abstract

We give a brief sketch of lattice structure function calculations and review previous results for the axial coupling gAg_A. We outline a new technique for treating fermions on the lattice that preserves chiral symmetry, domain wall fermions. Finally, we give preliminary results for the nucleon spectrum using this new technique. Remarkably, a large mass splitting between the NN and NN^*, roughly consistent with experiment, is produced in the calculation. These results are encouraging for proposed calculations of nucleon structure functions.
