论文摘要
我们研究了Quark-Lepton SU（4）统一统一的量规Leptoquark的当前和未来低能信号。完全考虑到夸克和卵子之间的一代混合的自由，我们编译了一个可观察到的目录，该目录目前构成了参数空间中排除的部分的边界 - 新物理学的第一个信号的热门候选者。我们还确定了为了检查当前允许的参数空间的一部分，以用于该目录中未包含的其他几个测量值所需的灵敏度。我们通过考虑了更多（以及更新的）实验测量以及更密集地扫描参数空间，从而改善了该主题的较旧类似作品。 此外，我们以类似的方式研究了SU（4）模型，这些模型具有少量的额外瘦素。我们还讨论了为了减轻中性流动B-膜衰变中当代差异所需的卵巢数量最少。
We study possible current and future low-energy signals of the gauge leptoquark in quark-lepton SU(4) unification à la Pati-Salam. Taking fully into account the freedom in the generation mixing between quarks and leptons, we compile a catalogue of observables which currently form a border of the excluded part of the parameter space - hot candidates for first signals of new physics. We also determine the sensitivity needed in order to inspect a currently allowed part of the parameter space for several other measurements which are not included in this catalogue. We improve older similar works on this topic by taking into account more (and more recent) experimental measurements and by scanning the parameter space more densely. Furthermore, we study in a similar manner the SU(4) models with a small number of generations of extra leptons. We also discuss the minimal number of leptons needed in order to alleviate the contemporary discrepancies in the neutral-current B-meson decays.
