论文摘要
在本文中，系统地分析了用leptoquarks和Diquarks补充的轴突模型。在这些后者的一些耦合中打开一些耦合，允许将Peccei-quinn对称性与Baryon（B）和Lepton（L）数字统一，因此轴突与三$ U（1）$对称性的自发断裂相关。讨论了B和L违规的所有可能的四个和六个特征模式，包括那些诱导质子衰变的人，$ΔB= 1 $ = 1 $和$Δl= \ pm 1，\ pm 3 $，中子 - 抗逆转录子振荡，$ΔB= 2 $，以及带有$Δl= 2 $ $ΔL= 2 $的Majorana Neutrino群众。还构建了一个或两个轴突磁场必然会出现在任何B和/或L违反操作员中的方案。然后，核子衰变必然涉及最终状态的轴，而中子 - 抗抗原振荡只会在轴子背景下发生。这可能会对中子寿命难题产生影响，更普遍地为新的现象学和宇宙学应用打开了大门。
In this paper, axion models supplemented by leptoquarks and diquarks are systematically analyzed. Turning on some couplings to and among these latter states permits to unify the Peccei-Quinn symmetry with baryon (B) and lepton (L) numbers, such that the axion becomes associated to the spontaneous breaking of the three $U(1)$ symmetries. All possible four- and six-fermion patterns of B and L violation are discussed, including those inducing proton decay, with $ΔB = 1$ and $ΔL = \pm 1, \pm 3$, neutron-antineutron oscillations with $ΔB = 2$, and Majorana neutrino masses with $ΔL = 2$. Scenarios in which one or two axion fields necessarily appear in any B and/or L violating operators are also constructed. Nucleon decays would then necessarily involve an axion in the final state, while neutron-antineutron oscillations would only happen in an axionic background. This could have implications for the neutron lifetime puzzle, and more generally, opens the door to new phenomenological and cosmological applications.
