Higher twists and color polarizabilities in the neutron

Abstract: Color polarizabilities of the neutron are extracted from data on the lowest moment of the spin-dependent structure function. New data in the resonance region from Jefferson Lab at , in combination with world data at higher , allow a systematic determination of the corrections, and provide the first constraints on 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 . [Copyright &y& Elsevier]
