论文摘要
CDF协作最近报告了$ W $ -BOSON质量测量的最新结果,显示了与标准模型预测的7σ$偏差。差异可能表明对费米耦合常数的新贡献。我们通过引入额外的标量,费米或向量场来研究标准模型的简单扩展。发现张力意味着如果与电子和/或MUON的新耦合是秩序统一的,则张力在多TEV量表中存在。
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.
