A model for lepton flavor violating non-standard neutrino interactions

We present a model for Lepton Flavor Violating (LFV) neutral current non-standard interactions of neutrinos with matter fields parameterized by $ε_{αβ}^f$ with $α\ne β$. Here, unlike the previous models, the ratios of the off-diagonal LFV elements of the effective NSI coupling to the diagonal lepton flavor conserving ones ({\it i.e.,} $(ε_{αβ}^f)^2/(ε_{αα}^f ε_{ββ}^f)$ ) are arbitrary. The model enjoys rich phenomenology, predicting invisible Higgs decay and new meson decay modes observable in upcoming experiments. The model for $ε_{μe}^f$ also predicts a $μ^-$ to $e^-$ conversion rate on nuclei accessible in the planned experiments.
