Low Seesaw Scale Solution for $M_W$ and $(g-2{)}_{\hat{I}}¼$

Abstract

In this short talk, we present a renormalizable model that can i) generate neutrino masses via a low-scale seesaw mechanism and ii) solve the long-standing $(g-2{)}_{\hat{I}}¼$ and the more recent CDF II $M_W$-anomalies. This is minimally achieved by introducing two sterile neutrinos and a single electroweak-doublet vector-like lepton, with masses $<2$ TeV. We focus on the one-generation scenario and the requirements to extend it to three generations.
