论文摘要
我们指出有必要考虑$β$ -DECAY在标准模型有效野外理论中的分辨率中可观察到的，这些分辨率超出了纯斜校正。我们证明了当前的全球分析，这些分析解释了$ w $ boson的质量异常，预示着大型，百分比，违反了第一行CKM Unitarity。我们调查了$ W $ -BOSON质量异常的解决方案在包括$β$ -DECAY约束后生存。
We point out the necessity to consider $β$-decay observables in resolutions of the $W$-boson anomaly in the Standard Model Effective Field Theory that go beyond pure oblique corrections. We demonstrate that present global analyses that explain the $W$-boson mass anomaly predict a large, percent-level, violation of first-row CKM unitarity. We investigate what solutions to the $W$-boson mass anomaly survive after including $β$-decay constraints.
