扩展标准模型中的可测轻子生成

Testable Leptogenesis in extended Standard Model

Sudhanwa Patra

摘要:

我们提出了一个新的最小扩展的标准模型与重马约拉纳费米子三重态($Σ$)和额外的标量二重态($η$),使跷跷板机制是辐射,可以在即将到来的加速器。本文讨论了中微子质量通过著名的通过重马约拉纳费米子三重态的跷跷板机制的起源。我们提出了一种轻子生成的机制,即费米子三重态中最轻的中性成分衰变为一个标准模型轻子二重态和一个额外的希格斯二重态。重要的是,这封信中讨论的稀薄起源场景可以是TeV级别的,因此可以在大型强子对撞机(LHC)上进行测试。我们还讨论了在我们的模型中一个可能的暗物质场景和费米子场$Σ$的可能现象。

英文摘要:

We have proposed a new minimal extension of the Standard Model with a heavy Majorana fermion triplet($Σ$) and an extra scalar doublet($η$) so that the seesaw mechanism is radiative and can be accessible at upcoming accelerators. The origin of neutrino mass via the famous seesaw mechanism through the heavy Majorana fermion triplet has been discussed. We have proposed a mechanism of leptogenesis by the decay of the lightest neutral component of the fermion triplet into a Standard Model lepton doublet and an extra Higgs doublet. The important thing is that the leptogenesis scenario discussed in this letter can be of TeV scale and hence can be testable at Large Hadron Collider(LHC). We have also discussed a possible dark matter scenario in our model and the possible phenomenology of the fermion field $Σ$.
