论文摘要
已经从自下而上的上下尝试了标准模型的扩展，但在很大程度上没有探索的中间立场。在本文中，使用Mathematica软件包lieart，我们详尽地列举了标准模型的嵌入，在产品量规组SU（a）XSU（a）XSU（b）XSU（c）中具有双基因式费米（C）的理论类别，而没有E6的发电机比E6更多，同时实现SM家族统一而不是重复。我们结合了简单的现象学约束，并找到了151个独特的模型，其中包括9个仅具有标准模型（BSM）粒子的矢量样粒子含量的模型，我们猜测这属于5个无限模型的家族。我们描述了潜在的最可行的模型：即，具有严格矢量样BSM含量的9条以及我们发现的29个模型，并不超过30个BSM手性颗粒。这些包括具有分数电荷颜色单线的型号，因此具有多个狄拉克电荷的磁性单极。后一个模型集合预测了手性颗粒，其质量在电动和将来的对撞机实验上可访问Electroweak量表附近。
Extensions of the Standard Model have been attempted from the bottom up and from the top down yet there remains a largely unexplored middle ground. In this paper, using the Mathematica package LieART, we exhaustively enumerate embeddings of the Standard Model within the class of theories with bifundamental fermions in product gauge group SU(a)XSU(b)XSU(c) with no more generators than E6, while achieving SM family unification rather than replication. We incorporate simple phenomenological constrains and find 151 unique models, including 9 that have only vector-like particle content beyond-the-Standard Model (BSM) particles, which we conjecture belong to 5 infinite families of such models. We describe the potentially most viable models: namely, the 9 with strictly vector-like BSM content along with the 29 models we found with no more than 30 additional BSM chiral particles. These include models with fractional electric charge color singlets, and hence magnetic monopoles with multiple Dirac charge. This latter collection of models predicts chiral particles with masses near the electroweak scale accessible to current and future collider experiments.
