Tests of flavor universality for neutrino-Z couplings in future neutrino experiments

We investigate the physics potential of the NuSOnG experiment to probe new physics contributions to Z nu nu couplings in muon-neutrino-electron elastic and neutral-current deep-inelastic scattering processes. We employ an effective Lagrangian approach and do not a priori assume universality of the coupling of neutrinos to Z. We obtain 95% C.L. limits on possible universality violating couplings.
