论文摘要
我们研究了三级相互作用对物质稳定性的影响，即在树上和何时共存的两个特定质子衰减拓扑中，它们在树和一环的情况下出现。我们证明，尽管通常存在循环抑制因子，但在质子衰减特征方面，一环拓扑比质子衰减的拓扑更重要。 We subsequently present detailed analysis of the triple-leptoquark interaction effects on the proton stability within one representative scenario to support our claim, where the scenario in question simultaneously features a tree-level topology that yields three-body proton decay $p\to e^+ e^+ e^-$ and a one-loop level topology that induces two-body proton decays $p\to π^0 e^+$ and $ p \至π^+ \barν$。我们还提供了所有非平凡的立方体和四分之一收缩的前阶质子衰变通道的综合列表，涉及三个标量leptoquark多重组，这些标量产生了我们兴趣的三重级数相互作用，在后一种情况下，标量型多重组之一是标准模型higgs higgs higgs higgs doublet。
We study the impact of triple-leptoquark interactions on matter stability for two specific proton decay topologies that arise at the tree- and one-loop level if and when they coexist. We demonstrate that the one-loop level topology is much more relevant than the tree-level one when it comes to the proton decay signatures despite the usual loop-suppression factor. We subsequently present detailed analysis of the triple-leptoquark interaction effects on the proton stability within one representative scenario to support our claim, where the scenario in question simultaneously features a tree-level topology that yields three-body proton decay $p\to e^+ e^+ e^-$ and a one-loop level topology that induces two-body proton decays $p\to π^0 e^+$ and $p\to π^+ \barν$. We also provide a comprehensive list of the leading-order proton decay channels for all non-trivial cubic and quartic contractions involving three scalar leptoquark multiplets that generate triple-leptoquark interactions of our interest, where in the latter case one of the scalar multiplets is the Standard Model Higgs doublet.
