论文摘要
我们提出了一个基于$ su（5）$ gauge理论的渐近大统一的最小模型，该理论是紧凑的$ s^1/（\ mathbb {z} _2 \ times \ times \ times \ mathbb {z}'_ 2）$ orbifold。量规耦合在没有超对称性的情况下运行到紫外线中的统一固定点。根据施工，费米子嵌入了不同的$ su（5）$散装字段中。结果，巴里昂的数量是保守的，因此可以防止质子衰减，最轻的kaluza-klein层由无法衰减到标准模型的新状态组成。我们表明，Yukawa联轴器可以在散装或本地化中，并延伸至紫外线中的渐近自由固定点。最轻的巨大状态可以发挥通过男性生成产生的暗物质的作用，以大约2.4美元的tev $ 2.4 $ tev产生。
We present a minimal model of asymptotic grand unification based on an $SU(5)$ gauge theory in a compact $S^1/(\mathbb{Z}_2 \times \mathbb{Z}'_2)$ orbifold. The gauge couplings run to a unified fixed point in the UV, without supersymmetry. By construction, fermions are embedded in different $SU(5)$ bulk fields. As a consequence, baryon number is conserved, thus preventing proton decay, and the lightest Kaluza-Klein tier consists of new states that cannot decay into standard model ones. We show that the Yukawa couplings can be either in the bulk or localized, and run to an asymptotically free fixed point in the UV. The lightest massive state can play the role of Dark Matter, produced via baryogenesis, for a Kaluza-Klein mass of about $2.4$ TeV.
