Abstract

We explore the physics potential of NuSOnG experiment to probe new physics contributions to $W\mu\nu_\mu$ couplings in inverse muon decay and charged current deep inelastic scattering processes. We show that NuSOnG provides two order of magnitude improvement in $W\mu\nu_\mu$ compared to LEP bound at 95% C.L.. Combining the results presented here with our earlier results, we obtain a significant improvement in the limits on neutrino flavor universality violation in neutrino-W and neutrino-Z couplings.
