Muon g − 2 and CKM unitarity in extra lepton models

Abstract We investigate the impact of extra leptons on observed tensions in the muon g − 2 and the first-row CKM unitarity. By introducing a new SU(2) L doublet lepton and a SU(2) L triplet lepton, we find that both of the tensions can be explained simultaneously under constraints from electroweak p...

description Abstract We investigate the impact of extra leptons on observed tensions in the muon g − 2 and the first-row CKM unitarity. By introducing a new SU(2) L doublet lepton and a SU(2) L triplet lepton, we find that both of the tensions can be explained simultaneously under constraints from electroweak precision observables and Higgs-boson decays. Our model could be tested by measurements of h → μμ at future collider experiments.
