Non-Standard neutral current Interactions (NSIs) of neutrinos with matter can alter the pattern of neutrino oscillation due to the coherent forward scattering of neutrinos on the medium. This effect makes long-baseline neutrino experiments such as NO nu A and DUNE a sensitive probe of beyond standard model (BSM) physics. We construct light mediator models that can give rise to both lepton flavor conserving as well as Lepton Flavor Violating (LFV) neutral current NSI. We outline the present phenomenological viability of these models and future prospects to test them. We predict a lower bound on Br(H -> mu tau) in terms of the parameters that can be measured by DUNE and NO nu A, and show that the hint for H -> mu tau in current LHC data can be accommodated in our model. A large part of the parameter space of the model is already constrained by the bound on Br(tau -> Z'mu) and by the bounds on rare meson decays and can be in principle fully tested by improving these bounds.
