有人观察到右手夸克与W的耦合吗?

Did one observe couplings of right-handed quarks to W ?

Jan Stern

摘要:

我认为非标准的EW耦合轻右手夸克W和Z建议在一个系统的非去耦自下而上的低能量有效的理论方法可能的扩展的标准模型。基于最近的测量和标量形状因子分析,讨论了K^ L_{mu3}衰变的新实验测试。一个成功的非线性光学适合的标准集Z极和其他数控数据。

英文摘要:

I consider non standard EW couplings of light right-handed quarks to W and Z suggested in a systematic non decoupling bottom-up low-energy effective theory approach to possible extensions of the Standard Model. New experimental tests in K^L_{mu3} decays based on recent measurements and scalar form factor analysis are discussed. A successful NLO fit to the standard set of Z-pole and other NC data is presented as well.
