在LHC上检验的右手中微子3-3-1模型的Higgs扇区

The Higgs sector of a 3-3-1 model with right-handed neutrinos to be tested at the LHC

Adrian Palcu

摘要:

在本文中,我们探讨了一些唯象的后果-将在大型强子对撞机测试-关于一个SU(3)xSU(3)xU(1)规范模型的标量部门与右手中微子。我们的分析是在一个特殊的理论方法处理规范模型与自发对称性破缺,其中一个单一的自由参数“a”最终仍然是要调整,一旦所有的标准模型的现象被恢复。它也被证明,这种特殊的方法是足够灵活,以适应传统的方法,其中三个VEV供应质量的规范玻色子和费米子,而三个伴随的中性标量生存的SSB,并参加各种相互作用。其中两个表现出层次m(H3)= 2 m(H2),质量低于SM标度246 GeV(独立于参数“a”),第三个非常重(取决于“a”),质量与整体破碎标度相当<phi>。然后<phi>利用1 - 10 TeV的一个合理的方案。

英文摘要:

We explore in this paper certain phenomenological consequences - to be tested at the LHC - regarding the scalar sector of a SU(3)xSU(3)xU(1) gauge model with right-handed neutrinos. Our analysis is performed in a particular theoretical approach of treating gauge models with spontaneous symmetry breaking in which a single free parameter 'a' finally remains to be tuned, once all the Standard Model phenomenology is recovered. It is also proved that this particular method is flexible enough as to accommodate the traditional approach in which three VEVs supply masses for gauge bosons and fermions, while three accompanying neutral scalars survive the SSB and take part in various interactions. Two of them exhibit a hierarchy m(H3) = 2m(H2) with masses below the SM scale 246 GeV (independently of the parameter 'a') and the third one coming out very heavy (depending on 'a'), at a mass comparable to the overall breaking scale <phi>. A plausible scenario implying <phi> in 1 - 10 TeV is then exploited.
