论文摘要
我们在无尺度的超对称翻转SU（5）肠模型中分析了核子衰减模式，并将它们与标准未弹出的超对称SU（5）肠模型中的尺寸-6算子对质子衰变的预测进行了对比。 We find that these GUT models make very different predictions for the ratios $Γ(p \to π^0 μ^+)/Γ(p \to π^0 e^+)$, $Γ(p \to π^+ \barν)/Γ(p \to π^0 e^+)$, $Γ(p \to K^0 e^+)/Γ(p \to π^0 e^+)$和$γ（p \至k^0μ^+）/γ（p \至π^0μ^+）$，以及对比率$γ（p \至π^0μ^+）/γ（p \ toπ^0 e^0 e^+）和$γ的预测（p \ to p \ toπ^0 E^+）$γ（p \ to p \ toπ^toπ^+bar bar bar C to^+bar C^+^（p toπ^+）（带有正常或逆点的光中微子质量的翻转SU（5）模型的变体。即将进行的大型中微子实验可能会有有趣的机会来探索质子和中子衰变中的肠道和风味物理学。
We analyze nucleon decay modes in a no-scale supersymmetric flipped SU(5) GUT model, and contrast them with the predictions for proton decays via dimension-6 operators in a standard unflipped supersymmetric SU(5) GUT model. We find that these GUT models make very different predictions for the ratios $Γ(p \to π^0 μ^+)/Γ(p \to π^0 e^+)$, $Γ(p \to π^+ \barν)/Γ(p \to π^0 e^+)$, $Γ(p \to K^0 e^+)/Γ(p \to π^0 e^+)$ and $Γ(p \to K^0 μ^+)/Γ(p \to π^0 μ^+)$, and that predictions for the ratios $Γ(p \to π^0 μ^+)/Γ(p \to π^0 e^+)$ and $Γ(p \to π^+ \barν)/Γ(p \to π^0 e^+)$ also differ in variants of the flipped SU(5) model with normal- or inverse-ordered light neutrino masses. Upcoming large neutrino experiments may have interesting opportunities to explore both GUT and flavour physics in proton and neutron decays.
