Neutrinophilic DM annihilation in a model with $U(1{)}_{L_{\mu }-L_{\tau }}\times U(1{)}_H$ gauge symmetry

Abstract

We propose a model with two different extra $U(1)$ gauge symmetries; muon minus tauon symmetry $U(1{)}_{L_{\mu }-L_{\tau }}$ and hidden symmetry $U(1{)}_H$. Then, we explain muon anomalous magnetic moment, semi-leptonic decays $b\to s\ell \bar{\ell }$, and dark matter. In particular, we find an intriguing dark matter candidate to be verified by Hyper-Kamiokande and JUNO in the future that request neutrinophilic DM with rather light dark matter mass$\sim \mathcal{O}(10)$ MeV.
