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 epsilon S alpha beta(f) with alpha not equal 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 (i.e., (epsilon alpha beta(f) )(2) (epsilon(f)(alpha)(alpha)epsilon(f)(beta)(beta))) 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 predict a mu(-) to e(-) conversion rate on nuclei accessible in the planned experiments. (C) 2020 The Author. Published by Elsevier B.V.
