论文摘要
我们研究了一个$ \ mathrm {so}（10）$ Grand Unification方案，其中复杂的10维标量多重组（包含标准模型（SM）Higgs Boson）完全存在于TEV量表。由此产生的低能模型是一种2-higgs-Doublet模型，该模型具有两个$ S_1 $ -Type leptoquarks。只有一个中间尺度，将pati-salam仪表组分解为SM，可以实现量规偶联的统一。质子稳定性是通过离散对称性确保的，从u（1）$ _ {\ mathrm {pq}} $ global Symmetry中剩下的剩余。与此对应于此破裂的U（1）$ _ {\ Mathrm {pq}} $相对应的轴为强大的CP问题提供了解决方案，并且也是重要的暗物质候选者。我们讨论$ r_ {d^{（*）}} $和$a_μ$异常的同时解释如何在模型中产生，并研究其一些现象学含义。
We investigate an $\mathrm{SO}(10)$ grand unification scenario where the complex 10-dimensional scalar multiplet, containing the Standard Model (SM) Higgs boson, resides at the TeV scale altogether. The resulting low-energy model is a 2-Higgs-doublet model augmented with two $S_1$-type leptoquarks. The gauge-coupling unification is achieved with only one intermediate scale at which the Pati-Salam gauge group is broken down to the SM. Proton stability is ensured by a discrete symmetry, leftover from the breaking of the U(1)$_{\mathrm{PQ}}$ global symmetry. The axion corresponding to this broken U(1)$_{\mathrm{PQ}}$ provides a solution to the strong CP problem, and also serves as an important dark matter candidate. We discuss how the simultaneous explanation for the $R_{D^{(*)}}$ and $a_μ$ anomalies comes about in the model, and investigate some of its phenomenological implications.
