A model for lepton flavor violating non-standard neutrino interactions

Abstract

We present a model for Lepton Flavor Violating (LFV) neutral current non-standard interactions of neutrinos with matter fields parameterized by ${\epsilon }_{\alpha \beta }^f$ with $\alpha \ne \beta$. 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.,} $({\epsilon }_{\alpha \beta }^f{)}^2/({\epsilon }_{\alpha \alpha }^f{\epsilon }_{\beta \beta }^f)$ ) are arbitrary. The model enjoys rich phenomenology, predicting invisible Higgs decay and new meson decay modes observable in upcoming experiments. The model for ${\epsilon }_{\mu e}^f$ also predicts a ${\mu }^{-}$ to $e^{-}$ conversion rate on nuclei accessible in the planned experiments.
