论文摘要
我们根据最近的$（g-2）_μ$测量，重新评估非标准三量规耦合，这是$（g-2）_ $的新晶格理论结果以及几种$ b $ - $ - decay模式的更新测量结果。在SMEFT的框架中，调用了三个Bosonic-dimension-6运算符以超越标准模型的物理及其对计算出的低能观测值的贡献。然后，对相应的威尔逊系数的约束从拟合到可观察到的当前实验界限得出，并将其与$ W^+ W^ - $和$ W^\ pm z $生产通道中的13个TEV LHC数据可用的最严格的限制。
We reassess non-standard triple gauge couplings in the light of the recent $(g-2)_μ$ measurement at FNAL, the new lattice theory result of $(g-2)_μ$ and the updated measurements of several $B$-decay modes. In the framework of SMEFT, three bosonic dimension-6 operators are invoked to parametrize physics beyond the Standard Model and their contributions to such low-energy observables computed. Constraints on the corresponding Wilson coefficients are then derived from fits to the current experimental bounds on the observables and compared with the most stringent ones available from the 13 TeV LHC data in the $W^+ W^-$ and $W^\pm Z$ production channels.
