唯一的Higgs偶态中带电Higgs场的非零VEV不能产生中微子质量的原因

Why Neutrino Masses Cannot Arise from Nonzero VEV of Charged Higgs Field in the Only Higgs Doublet

Jianlong Lu

摘要:

[arXiv:2003.12069]提出了一个中微子质量产生方案,其中小的非零中微子质量来自粒子物理标准模型中Higgs偶线中带电Higgs场的非零真空期望值(VEV)。然而,带电Higgs场的非零VEV的引入意味着电弱理论中的${\rm U}(1)$对称性破缺,从而导致电荷的不守恒和光子质量的非零。通过比较文献[1]中带电Higgs场和中性Higgs场的VEV之比与目前实验上光子质量上限所限制的VEV之比,我们证明该方案是不可行的。

英文摘要:

A scheme of neutrino mass generation is proposed by [arXiv:2003.12069], in which the small nonzero neutrino masses come from nonzero vacuum expectation value (VEV) of the charged Higgs field in the Higgs doublet in the Standard Model of particle physics (SM). However, the introduction of nonzero VEV for the charged Higgs field implies broken ${\rm U}(1)$ symmetry in the electroweak theory, which leads to non-conservation of electric charge and nonzero mass of photon. By comparing the predicted ratio of VEVs of charged Higgs field and neutral Higgs field in [1] with the ratio constrained by the present experimental upper bound of photon mass, we show that this scheme does not work.
