摘要

我们研究了在S1/（Z2×Z2’）轨道上紧化的五维规范对称破缺的真空稳定性。我们考虑了体中的SU(N), Sp(N)， SO（2N）和SO（2N+1）理论，并提供了导致稳定轨道和相应对称破缺模式的可能宇称赋值的详尽分类。我们将这些结果用于寻找可行的渐近大统一理论（aGUT），并测试了基于SU(6)和SU(8)的模型的稳定性准则。因此，我们确定了两个可行的agut：一个唯一的SU(6)途径通向标准模型，一个SU(8)模型通向中间的patii - salam部分统一。2025年由美国物理学会出版

General vacuum stability of orbifold gauge breaking and application to asymptotic grand unification

We examine the vacuum stability of gauge symmetry breaking in five dimensions, compactified on the S1/(Z2×Z2′) orbifold. We consider SU(N), Sp(N), SO(2N), and SO(2N+1) theories in the bulk, and provide an exhaustive classification of possible parity assignments that lead to stable orbifolds and of the corresponding symmetry breaking patterns. We use these results in the search for viable asymptotic grand unification theories (aGUT), testing the stability criteria on models based on SU(6) and SU(8). As a result, we identify two viable aGUTs: a unique SU(6) pathway down to the Standard Model, and one SU(8) model leading to an intermediate Pati-Salam partial unification.
