论文摘要
CDF II实验已提供了用于测量W玻色子质量的新报告。 W玻色子质量的测量值为$ M_W^{\ text {cdf ii}} = 80.4335 \ pm 0.0094 $ GEV，显示出$7σ$与标准模型预测的偏差，而其他高能实验组，例如，E.G.，Atlas和D0 II，均显示为一致的结果。假设CDF II的测量是正确的，我们讨论了解释HIGGS三重态模型中异常的可能性。我们发现，可以根据electroweak rho参数的约束来解释异常，有效的弱混合角，Leptonic $ z $衰减的部分宽度以及当前在LHC进行的直接搜索，当非零质量差异在三胞胎的质量差异和类似三重的higgs bosons and vacuum the Vacuum的预期和$ cal $ ge $ cal cal cact cact cact of cal of cal of cal of cal of cal of cal of cal of cal of cact（ $ {\ cal o}（1）$ GEV。
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 $m_W^{\text{CDF II}} = 80.4335 \pm 0.0094$ 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 ${\cal O}(100)$ GeV and ${\cal O}(1)$ GeV, respectively.
