论文摘要
我们研究了$（10）$ Grand Unified Theory（GUT）中的质子寿命，该理论（肠道）在肠道量表下具有左右（LR）对称仪表理论。特别是，我们专注于LR对称模型中没有Bi-Doubleet Higgs字段的最小模型，该模型将LR破坏规模的规模约为$ 10^{10 \ text { - } 12} $ gev。质子衰减运算符的Wilson系数比最小$ su（5）$ ut模型中的质子衰减算子的系数要大得多，尤其是当标准模型Yukawa相互作用是通过集成额外的矢量样乘积而产生的。结果，我们发现质子寿命可以在Hyper-Kamiokande实验的范围内，即使肠量规玻色子质量在$ 10^{16 \ text { - } 17} $ GEV范围内。我们还表明，额外的矢量样质量可以通过与斧头暗物质方案一致的peccei-quinn对称性破裂产生。
We study the proton lifetime in the $SO(10)$ Grand Unified Theory (GUT), which has the left-right (LR) symmetric gauge theory below the GUT scale. In particular, we focus on the minimal model without the bi-doublet Higgs field in the LR symmetric model, which predicts the LR-breaking scale at around $10^{10\text{--}12}$ GeV. The Wilson coefficients of the proton decay operators turn out to be considerably larger than those in the minimal $SU(5)$ GUT model especially when the Standard Model Yukawa interactions are generated by integrating out extra vector-like multiplets. As a result, we find that the proton lifetime can be within the reach of the Hyper-Kamiokande experiment even when the GUT gauge boson mass is in the $10^{16\text{--}17}$ GeV range. We also show that the mass of the extra vector-like multiplets can be generated by the Peccei-Quinn symmetry breaking in a consistent way with the axion dark matter scenario.
