$W$ -玻色子质量异常的新物理解释

New physics interpretation of $W$-boson mass anomaly

Motoi Endo, Satoshi Mishima

摘要:

CDF合作最近报告了一个关于$W$ -玻色子质量测量的更新结果,显示了$7σ$与标准模型预测的偏差。这种差异可能表明对费米耦合常数有新的贡献。我们通过引入额外的标量场、费米子场或矢量场来研究标准模型的简单扩展。结果表明,如果与电子和μ子的耦合是有序统一的,那么这种张力就意味着新的物理存在于多TeV的尺度中.

英文摘要:

The CDF collaboration has recently reported an updated result on the $W$-boson mass measurement, showing a $7σ$ deviation from the standard model prediction. The discrepancy may indicate new contributions to the Fermi coupling constant. We study simple extensions of the standard model by introducing an extra scalar, fermion or vector field. It is found that the tension implies the new physics existing in multi-TeV scales if the new coupling to the electron and/or muon is of order unity.
