Charged-current reactions in the NuSOnG and a test of neutrino-W couplings

We explore the physics potential of the NuSOnG experiment to probe new physics contributions to W mu v(mu) couplings in inverse muon decay and charged-current deep-inelastic scattering processes. We show that NuSOnG provides two orders of magnitude improvement in W mu v(mu) compared to LEP bound at 95% CL. 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.
