我们在超对称场论和全局一致的 D 膜模型中研究了各种轴子的可行场景。 Peccei-Quinn 对称性与反常 U(1) 对称性相关，该对称性在弦尺度上获得质量，但在低能量下仍保持微扰全局对称性。推导了来自 F-、D- 和软破缺项的标量希格斯轴子势的起源，并提出了 II 型东方褶皱中全局相交 D6 膜模型的两个标准模型示例，它们的不同之处在于希格斯扇区和隐藏扇区的实现，后者对于软超对称破缺项特别重要。
We investigate viable scenarios with various axions in the context of supersymmetric field theory and in globally consistent D‐brane models. The Peccei‐Quinn symmetry is associated with an anomalous U(1) symmetry, which acquires mass at the string scale but remains as a perturbative global symmetry at low energies. The origin of the scalar Higgs‐axion potential from F‐, D‐ and soft breaking terms is derived, and two Standard Model examples of global intersecting D6‐brane models in Type II orientifolds are presented, which differ in the realisation of the Higgs sector and in the hidden sector, the latter of which is of particluar importance for the soft supersymmetry breaking terms.
