Parity-Violating $\Delta$(1232) Electroweak Production: Axial Structure and New Physics

Abstract

We consider prospects for studying the parity-violating electroweak excitation of the $\Delta (1232)$ resonance with polarized electron scattering (see nucl-th/9801025). We discuss the experimental feasibility and theoretical interpretability of such a measurement as well as the prospective implications for hadron structure theory. We also analyze the extent to which a PV $N\to \Delta$ measurement could constrain various extensions of the Standard Model.
