论文摘要
CDF-II协作对$ W $ BOSON质量的高精度测量表明，除了标准模型之外，新物理学的贡献。解释异常$ w $玻色子质量的简约方法之一是引入无charge的真实$ su（2）_l $三重态标量，其真空期望值明显地在树级上有助于$ w $ boson质量，而$ z $ boson块则保持不变。这样的三重态可以自然地嵌入单重骨术模型中，以用于一个环中的深色扇形颗粒产生的一个环中微子质量。我们讨论了该模型的详细现象学，获得了与CDF-II $ W $ BOSON质量测量相一致的参数空间。还分析了暗物质以及$ s $，$ t $，$ u $参数的约束。
The recent high precision measurement of $W$ boson mass by CDF-II collaboration points to the contribution(s) of new physics beyond the Standard Model. One of the minimalistic ways to account for the anomalous $W$ boson mass is by introducing a hyperchargeless real $SU(2)_L$ triplet scalar whose vacuum expectation value explicitly contributes to the $W$ boson mass at the tree level while the $Z$ boson mass remains the same. Such a triplet can be naturally embedded in a singlet-triplet scotogenic model for one loop neutrino mass generated by dark sector particles running in the loop. We discuss the detailed phenomenology of the model, obtaining the parameter space consistent with the CDF-II $W$ boson mass measurements. The dark matter as well as the constraints comings from $S$, $T$, $U$ parameters are also analyzed.
