摘要
我们研究了一种 大统一场景,其中含有标准模型(SM)希格斯玻色子的复 10 维标量多重态整体处于 TeV 能标。所得低能模型是一个双希格斯二重态模型,并附加两个 型轻夸克。规范耦合统一仅通过一个中间能标实现,在该能标处 Pati-Salam 规范群破缺为 SM。质子稳定性由离散对称性保证,该对称性源自 U(1) 整体对称性破缺的剩余。对应于该破缺 U(1) 的轴子提供了强 CP 问题的解,并且也是重要的暗物质候选者。我们讨论了模型中如何同时解释 与 反常,并研究了其若干唯象含义。

20 pages, 4 figures, 5 tables. Significant improvements in the text and results, which are now based on the latest data for the $a_\mu$ and $R_{D^{(*)}}$ anomalies. A thorough explanation of the validity of the low-energy model through RGE running of the Yukawa couplings has also been included
