稀薄成因与III型See-Saw的LHC物理

Leptogenesis and LHC Physics with Type III See-Saw

Shao-Long Chen, Xiao-Gang He

摘要:

跷跷板机制提供了一个很好的方法来解释为什么中微子的质量比它们的带电轻子伙伴轻得多。它也提供了一个很好的方式来解释重子不对称性在我们的宇宙通过leptogenesis机制。在这次演讲中,我们回顾了1989年提出的跷跷板模型中的leptogenesis和LHC物理,现在称为III型跷跷板模型。在这个模型中,引入了$SU(2)_L$三重态轻子,其中中性粒子扮演跷跷板的角色。三重态轻子与伴子具有标准模型规范相互作用,从而产生许多新的特征。这些粒子的规范相互作用使其更容易在低质量下发生,低至TeV是可能的。规范相互作用也使得在LHC上产生和探测三重态轻子成为可能。由于III型跷跷板的跷跷板机制和leptogenesis可能会在LHC进行测试。

英文摘要:

The See-Saw mechanism provides a nice way to explain why neutrino masses are so much lighter than their charged lepton partners. It also provides a nice way to explain baryon asymmetry in our universe via the leptogenesis mechanism. In this talk we review leptogenesis and LHC physics in a See-Saw model proposed in 1989, now termed the Type III See-Saw model. In this model, $SU(2)_L$ triplet leptons are introduced with the neutral particles of the triplets playing the role of See-Saw. The triplet leptons have charged partners with standard model gauge interactions resulting in many new features. The gauge interactions of these particles make it easier for leptognesis with low masses, as low as a TeV is possible. The gauge interactions also make the production and detection of triplet leptons at LHC possible. The See-Saw mechanism and leptogenesis due to Type III See-Saw may be tested at LHC.
