A testable radiative neutrino mass model without additional symmetries and Explanation for the $b\to s{\ell }^{+}{\ell }^{-}$ anomaly

Abstract

We propose a one-loop radiative Majorana-type neutrino-mass matrix without any kind of additional symmetries by introducing two leptoquark-like bosons only. In this scenario, we show that the anomaly appearing in the process $b\to s\ell \bar{\ell }$ can be explained without any conflicts against various constraints such as lepton-flavor violations, flavor-changing neutral currents, oblique parameters $\Delta S,\Delta T$, and the Drell-Yan process. We make the predictions for the flavor-violating lepton-pair production ($e\mu$, $e\tau$, and $\mu \tau$) at the LHC, as well as the cross sections for pair production of these leptoquark-like bosons.
