论文摘要

我们对场景进行了完整的分析,这些场景具有辐射产生的中微子肿块,这些中微子可能发生在最小的超对称标准模型中,具有低尺寸的右手中微子。对于简洁起见,我们将这样的模型称为$ν_r$ MSSM。我们特别注意超对称性(SUSY)对环路诱导的中微子质量的影响,通过在弱和风味碱基中进行计算。特别是,我们发现观察到的轻中微子肿块的较小性自然可能是由于近乎超对称单元中微子扇形的柔软的susy筛分效应。讨论了$ν_r$ MSSM中这种筛选现象及其最小扩展的深刻现象学和宇宙学的含义。

We present a complete analysis of scenarios with radiatively generated neutrino masses that may occur in the Minimal Supersymmetric Standard Model with low-scale right-handed neutrinos. For brevity, we call such a model the $ν_R$MSSM. We pay particular attention to the impact of the non-renormalization theorem of supersymmetry (SUSY) on the loop-induced neutrino masses, by performing our computations in the weak and flavour bases. In particular, we find that the smallness of the observed light neutrino masses may naturally arise due to a soft SUSY-screening effect from a nearly supersymmetric singlet neutrino sector. The profound phenomenological and cosmological implications that may originate from this screening phenomenon in the $ν_R$MSSM and its minimal extensions are discussed.
