The Contribution of Charged Bosons with Right-Handed Neutrinos to the Muon g-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 the twin Higgs models with the joint constraints of the Higgs global fit data, the precision electroweak data, the leptonic flavor changing decay \mu \to e\gamma, and the mass requirement of the heavy gauge bosons. It comes out with the conclusion that some parameters such as the coupling of charged Higgs to the lepton y_\mu, the top Yukawa y_t, and the heavy gauge boson coupling to the lepton V_\mu are constrained roughly in the range of 0.12\lesssim y_\mu\lesssim 0.4, 0.4\lesssim y_t\lesssim 0.9, and 0.47\lesssim V_\mu\lesssim 1, respectively.
