Polarized lepton-hadron scattering in asymptotically free gauge theories

We analyze polarized deep inelastic electron and neutrino scattering in asymptotically free gauge theories of the strong interactions. We compute the logarithmic deviations from Bjorken scaling in the moment sum rules for the structure functions due to the leading twist-2 and -3 operators that control the light-cone expansion. We also consider continuations to the elastic limit and to the Regge region.
