TeV尺度跷跷板机构的现象学

Phenomenology of TeV Scale See-Saw Mechanism

Emiliano Molinaro

摘要:

我们回顾了标准模型的I型跷跷板扩展的低能约束,其中与轻子数违反相关的新物理的尺度可以在当前的对撞机搜索中进行探索。在这种情况下,标准模型轻子与重右手中微子的带电流和中性流弱相互作用的味结构,提供了新的物理贡献,基本上是由中微子振荡参数决定的。轻子扇区中不同低能观测量之间的相关性显现出来,这可能为低能(TeV尺度)跷跷板机制提供了一个引人注目的间接证据。

英文摘要:

We review the low energy constraints on type I see-saw extensions of the Standard Model in which the scale of new physics, associated to lepton number violation, can be probed at current collider searches. In such scenarios, the flavour structure of the charged current and neutral current weak interactions of the Standard Model leptons with the heavy right-handed neutrinos, which provide the contribution of new physics, is essentially determined by the neutrino oscillation parameters. Correlations among different low energy observables in the lepton sector emerge, which may provide a striking indirect evidence of low energy (TeV scale) see-saw mechanism.
