LHC上中微子质量产生和三电荷希格斯玻色子的新机制

New Mechanism for Neutrino Mass Generation and Triply Charged Higgs Boson at the LHC

S. Nandi

摘要:

在这次演讲中,我提出了一种通过7维算符产生中微子质量的新机制:11 HH(H*H)/M^3。由此导出了轻中微子质量的新公式m_v ~v^4/M^3。这与通常的跷跷板公式m_v ~v^2/M不同。新物理学的规模自然可以在TeV规模。产生d=7算符的微观理论有一个同位旋为3/2的希格斯多重态Φ,其中包含一个三重电荷的希格斯玻色子玻色子,质量约为~TeV或更小。这些粒子可以在LHC(也可能在Tevatron)中产生,具有独特的多W和多轻子终态。对于参数空间的某些选择,这些粒子也可以是长寿命的,具有位移顶点的可能性,或者甚至逃离检测器。它们的轻子衰变模式携带着关于中微子质量等级性质的信息。

英文摘要:

In this talk, I present a new mechanism for the generation of neutrino masses via dimension 7 operators: llHH(H*H)/M^3. This leads to new formula for the light neutrino masses, m_ν~v^4/M^3. This is distinct from the usual see-saw formulae: m_ν~v^2/M. The scale of new physics can naturally be at the TeV scale. Microscopic theory that generated d=7 operator has an isospin 3/2 Higgs multiplet Φ, which contains a triply charged Higgs boson with mass around ~TeV or less. These particles can be produced at the LHC (and possibly at the Tevatron) with distinctive multi-W and multi-lepton final states. For some choice of the parameter space, these particles can also be long-lived with the possibility of displaced vertices, or even escaping the detector. Their leptonic decay modes carry information about the nature of the neutrino mass hierarchy.
