Abstract

The generalized forward spin polarizabilities γ0 and δLT f the neutron have been extracted for the first time in a Q2 range from 0.1 to 0.9 GeV2. Since γ0 is sensitive to nucleon resonances and δLT is insensitive to the Δ resonance, it is expected that the pair of forward spin polarizabilities should provide benchmark tests of the current understanding of the chiral dynamics of QCD. The new results on δLT how significant disagreement with chiral perturbation theory calculations, while the data for γ0 at low Q2 re in good agreement with a next-to-leading-order relativistic baryon chiral perturbation theory calculation. The data show good agreement with the phenomenological MAID model.
