Abstract

We investigate simplified models involving an inert scalar triplet and vectorlike leptons that can account for the muon $g\ensuremath{-}2$ anomaly. These simplified scenarios are embedded in a model that features W' and Z' bosons, which are subject to stringent collider bounds. The constraints coming from the muon $g\ensuremath{-}2$ anomaly are put into perspective with collider bounds, as well as bounds coming from lepton flavor violation searches. The region of parameter space that explains the $g\ensuremath{-}2$ anomaly is shown to be within reach of lepton flavor violation probes and future colliders such as HL-LHC and HE-LHC.
