论文摘要
我们将SU（5）与II型SEESAW机制作为中微子质量的SU（5）大统一的SU（5）大统一的最小非对称模型重新审视。施加了量规耦合统一和质子寿命边界的要求，我们执行贝叶斯拟合，并在超出标准模型颗粒的质量尺度上获得可靠的定量信息。然后，我们研究了由II型标量三重态及其SU（5）伙伴引起的Lepton-Flavour-violating（LFV）过程，表明即将搜索不同LFV可观察物的搜索相互作用可以提供有关新颗粒质量的其他信息，以及对中子参数的非微不足道约束。
We revisit minimal non-supersymmetric models of SU(5) Grand Unification with the type II seesaw mechanism as the origin of neutrino masses. Imposing the requirement of gauge coupling unification and the proton lifetime bounds, we perform a Bayesian fit and obtain robust quantitative information on the mass scales of the beyond the Standard Model particles. We then study lepton-flavour-violating (LFV) processes induced by the type II scalar triplet and its SU(5) partners, showing that the interplay of upcoming searches for different LFV observables can provide additional information on the masses of the new particles, as well as non-trivial constraints on neutrino parameters.
