Polarized Structure Functions and the GDH Integral from Lattice QCD
Abstract
The Gerasimov-Drell-Hearn integral IGDH(Q2), and its relation to polarized nucleon structure functions, is discussed from the lattice perspective. Of particular interest is the variation of IGDH(Q2) with Q2, and what it may teach us about the origin and magnitude of higher-twist contributions.
