A.B. Balantekin, I. Sahin, and B. Sahin
TL;DR
This paper explores how future neutrino experiments like NuSOnG can test for deviations from flavor universality in Z-neutrino interactions, providing limits on new physics effects.
Contribution
It introduces a model-independent approach to constrain flavor-dependent Z-neutrino couplings using upcoming experimental data.
Findings
Set 95% C.L. limits on non-universal Z-neutrino couplings.
Demonstrated the sensitivity of NuSOnG to flavor-violating effects.
Highlighted the importance of precision measurements in neutrino physics.
Abstract
We investigate the physics potential of NuSOnG experiment to probe new physics contributions to Z-neutrino-neutrino 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.
