Leading-Log Effects in the Resonance Electroweak Form Factors

الأصل · EN

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.
