将规范场的半经典局域化机制与 5 个时空维度的简单规范理论中的畴壁背景相结合，我们研究了几何希格斯机制，其中规范对称性的自发破坏来自于畴壁的分裂。详细研究了现象学上有趣的情况的质谱，该情况是在重合的三重态和二重态畴壁的分裂配置上实现的。我们使用模量近似在一般背景下推导了低能有效理论，其中有效场之间的所有非线性相互作用最多可捕获 2 个导数。我们观察到模型中的畴壁与超弦理论中的 D 膜之间存在新颖的相似性。
Combining the semiclassical localization mechanism for gauge fields withdomain wall background in a simplegauge theory in 5 space-time dimensions, we investigate the geometric Higgs mechanism, where a spontaneous breakdown of the gauge symmetry comes from splitting of domain walls. The mass spectra are investigated in detail for the phenomenologically interesting case, which is realized on a split configuration of coincident triplet and doublet of domain walls. We derive a low-energy effective theory in a generic background using the moduli approximation, where all nonlinear interactions between effective fields are captured up to 2 derivatives. We observe novel similarities between domain walls in our model and D-branes in superstring theories.
