Beta-decay implications for the W-boson mass anomaly

Vincenzo Cirigliano, Wouter Dekens, Jordy de Vries, Emanuele Mereghetti, Tom Tong

摘要:

指出了在标准模型有效场论中,在超越纯斜修正的$W$玻色子反常的分辨率中考虑$β$衰变观测量的必要性。我们表明,目前的全球分析,解释$W$ -玻色子质量异常预测一个大的,高水平的,违反第一行CKM么正性。我们调查什么解决方案$W$玻色子质量异常生存后,包括$β$衰变约束。

英文摘要:

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.
