The generalized forward spin polarizabilities of the neutron were measured. The forward spin polarizabilities γ0 and δLT of the neutron were found to be extracted for the first time in a Q2 range from 0.1 to 0.9 GeV2. As γ0 was sensitive to nucleon resonance and δLT was insensitive to the δ resonance resonance, it was the expected that the pair of forward spin polarizabilites should provide benchmark test. The results show significant disagreement with the next-to-leading-order relativistic baryon chiral perturbation theory calculation.
