Twin Anomaly in a Minimal Extension of Inert 2HDM
摘要
In this article, we address the observed discrepancies in the W-boson mass and muon anomalous magnetic moment in the Inert Two Higgs Doublet Model (I2HDM) extended by a complex scalar field singlet under the SM gauge group. The model is constrained from the existing LEP data and the measurements of partial decay widths to gauge bosons at LHC. It is shown that a large subset of the constrained parameter space of the model can accommodate both, the experimentally measured as well as SM global fit value of W-boson mass while simultaneously explaining the observed muon \(g-2\) anomaly.
