最小辐射中微子质量

Minimal Radiative Neutrino Masses

Christiane Klein, Manfred Lindner, Sebastian Ohmer

摘要:

我们进行了一个系统的搜索中微子质量模型,只有辐射产生的维5温伯格算子。因此,我们不允许在标准模型规范对称性之外有额外的对称性,我们将自己限制在极小模型。我们还包括稳定的分数带电和有色粒子在我们的搜索。此外,我们证明,有一个独特的模型与三个新的费米子表示,不需要新的标量产生中微子质量在循环水平。这个模型进一步有一个潜在的暗物质候选者,并通过费米子阶梯引入了中微子质量环抑制的一般机制

英文摘要:

We conduct a systematic search for neutrino mass models which only radiatively produce the dimension-5 Weinberg operator. We thereby do not allow for additional symmetries beyond the Standard Model gauge symmetry and we restrict ourselves to minimal models. We also include stable fractionally charged and coloured particles in our search. Additionally, we proof that there is a unique model with three new fermionic representations where no new scalars are required to generate neutrino masses at loop level. This model further has a potential dark matter candidate and introduces a general mechanism for loop-suppression of the neutrino mass via a fermionic ladder
