Leading-Log Effects in the Resonance Electroweak Form Factors
Abstract
We study log corrections to inelastic scattering at high Bjorken x for Q2 from 1 to 21 GeV2. At issue is the presence of log corrections, which can be absent if high x scattering has damped gluon radiation. We find logarithmic correction of the scaling curve extrapolated to low Q2 improves the duality between it and the resonance plus background data in the Delta region, indicating log corrections exist in the data. However, at W > 2 GeV and high x, the data shows a (1-x)3 form. Log corrections in one situation but not in another can be reconciled by a W- or Q2- dependent higher twist correction.
