Abstract

We study a combination of amplitudes for neutrino scattering that can isolate a (gauge-invariant) difference of chirality-preserving neutrino electroweak radii for [Formula Presented] and [Formula Presented] This involves both photon and [Formula Presented] exchange contributions. It is shown that the construction singles out the contributions of the hypercharge gauge field [Formula Presented] in the standard model. We comment on how gauge-dependent terms from the charge radii cancel with other terms in the relative electroweak radii.
