论文摘要
Higgs三胞胎字段的真空期望值$ v_s $Δ$带有两个单位的Lepton Number $ l $诱导中微子群众$ \ propto v_s $。 $δ$的中性成分产生了两个higgs粒子，一个伪call $ a $和标量$ s $。 $δ$的最通用的可重新计算higgs潜在的$ v $和标准模式higgs doublet $φ$不允许允许$ a $ a $ a $ a $ a或$ s $的质量很小，$ v_s $，而另一个质量则足以使decay $ z \ z $ z $ yep a s $与lep 1数据组成。我们提出了一个在$ v $中具有附加尺寸的模型，其中此功能不存在，并且可以选择$ a $ a或$ s $。随后，我们提出该模型作为宇宙学异常的补救措施，即在宇宙微波背景下观察到的张量与尺度模式比之间的张力与在不同宇宙学量表下测得的哈勃常数的不同值之间的张力。此外，如果$δ$主要伴侣与第三代双线$l_τ=（ν_τ，τ）$，则可以解释IceCube $ν_τ$事件的赤字。单一充电的三胞胎希格斯玻色子分别比280 GEV和400 GEV轻，可以在LHC找到。
The vacuum expectation value $v_s$ of a Higgs triplet field $Δ$ carrying two units of lepton number $L$ induces neutrino masses $\propto v_s$. The neutral component of $Δ$ gives rise to two Higgs particles, a pseudoscalar $A$ and a scalar $S$. The most general renormalizable Higgs potential $V$ for $Δ$ and the Standard-Model Higgs doublet $Φ$ does not permit the possibility that the mass of either $A$ or $S$ is small, of order $v_s$, while the other mass is heavy enough to forbid the decay $Z\to A S$ to comply with LEP 1 data. We present a model with additional dimension-6 terms in $V$, in which this feature is absent and either $A$ or $S$ can be chosen light. Subsequently we propose the model as a remedy to cosmological anomalies, namely the tension between observed and predicted tensor-to-scalar mode ratios in the cosmic microwave background and the different values of the Hubble constant measured at different cosmological scales. Furthermore, if $Δ$ dominantly couples to the third-generation doublet $L_τ=(ν_τ,τ)$, the deficit of $ν_τ$ events at IceCube can be explained. The singly and doubly charged triplet Higgs bosons are lighter than 280 GeV and 400 GeV respectively, and could be found at the LHC.
