Nucleon Spin Structure at Low Energies

Abstract : We apply chiral effective field theory with explicit Δlpar;1232) degrees of freedom to study double virtual Compton scattering at the photon point. Generalized spin polarizabilities are calculated up to order ε3 in the covariant small scale expansion. Systematic inclusion of Δ degrees of freedom drasticaly improves the theoretical predictions.
