Abstract

We will examine the muon $$g-2$$

anomaly with the background of the Higgs global fit data in the framework of the Left-Right Twin Higgs (LRTH) Models. The joint constrains of the precision electroweak data, the 125 GeV Higgs data, the leptonic flavor changing decay $\mu \rightarrow e\gamma$ decays, and the mass requirement of the right-handed neutrino $\nu _R$ , the vector-like top partner T and the heavy gauge boson $$W_H$$

, $m_{\nu _R}>m_T>m_{W_H}$ , are all considered in our calculation. Furthermore, since the neutral scalar $\phi ^0$ may be lighter than the 125 GeV Higgs, the direct searches from the $h\rightarrow \phi ^0\phi ^0$ channels can impose stringent upper limits on Br $(h\rightarrow \phi ^0\phi ^0)$ , which will reduce the allowed region of $m_{\phi ^0}$ and f, the vacuum expectation value of the SM right-handed Higgs $$H_R$$

. It is concluded that the muon g-2 anomaly can be explained in the region of 700 GeV $\le f\le$ 1100 GeV, 13 GeV $\le m_{\phi ^0}\le$ 55 GeV, 100 GeV $\le m_{\phi ^\pm }\le$ 900 GeV, $m_{\nu _R}\ge$ 15 TeV, and 200 GeV $\le M\le$ 800 GeV, after imposing all the constraints mentioned above, where M here means the mass mixing coefficient $M \bar{q}_Lq_R$ , allowed by gauge invariance.
