Implication of the W boson mass anomaly at CDF II in the Higgs triplet model with a mass difference
A new report for the measurement of the W boson mass has been provided by the CDF II experiment. The measured value of the W boson mass is given to be mWCDF II=80.4335±0.0094 GeV which shows 7σ deviation from the standard model prediction, while the other groups of high energy experiments, e.g., ATL...

| description | A new report for the measurement of the W boson mass has been provided by the CDF II experiment. The measured value of the W boson mass is given to be mWCDF II=80.4335±0.0094 GeV which shows 7σ deviation from the standard model prediction, while the other groups of high energy experiments, e.g., ATLAS and D0 II, show consistent results with the latter. Assuming that the measurement at CDF II is correct, we discuss the possibility to explain the anomaly in the Higgs triplet model. We find that the anomaly can be explained under the constraints from the electroweak rho parameter, the effective weak mixing angle, the partial width of the leptonic Z decay and current direct searches at LHC when non-zero mass differences among the triplet-like Higgs bosons and the vacuum expectation value of the triplet Higgs field are taken to be O(100) GeV and O(1) GeV, respectively. |
