论文摘要
[Arxiv：2003.12069]提出了中微子质量产生的方案，其中小的非零中微子质量来自粒子物理学模型（SM）中HIGGS倍增中带电的Higgs场的非零真空期望值（VEV）。然而，引入带电的希格斯字段的非零VEV意味着损失的$ {\ rm u}（1）$对称性在电动eakey理论中导致电荷不信任和光子的非零质量。通过比较[1]中带电的希格斯场和中性希格斯场的VEV的预测比例与受光子质量的当前实验上限约束的比率，我们表明该方案不起作用。
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.
