The Contribution of Charged Bosons with Right-Handed Neutrinos to the Muon <i>g</i> − 2 Anomaly in the Twin Higgs Models

Abstract

We examine the charged boson and right-handed neutrino contribution to the muon g−2 anomaly in twin Higgs models with joint constraints of Higgs global fit data, precision electroweak data, leptonic flavor-changing decay μ→eγ, and the mass requirement of heavy-gauge bosons. It comes with the conclusion that some parameters, such as the coupling of charged Higgs to the lepton yμ, the top Yukawa yt, and heavy-gauge boson coupling to the lepton Vμ are constrained roughly in the range of 0.12≲yμ≲0.4, 0.4≲yt≲0.9, and 0.47≲Vμ≲1, respectively.
