    Abstract:
    Color polarizabilities of the neutron are extracted from data on the lowest moment of the spin-dependent g1 structure function. New data in the resonance region from Jefferson Lab at Q2≲1 GeV2, in combination with world data at higher Q2, allow a systematic determination of the 1/Q2 corrections, and provide the first constraints on 1/Q4 corrections. The results suggest that higher-twist effects in the neutron are small, and that quark-hadron duality may be approximately valid, even down to Q2∼1 GeV2. © 2005 Elsevier B.V. All rights reserved.
