如果低能有效理论在量子引力理论中没有任何一致的紫外线完整性，那么它就被认为是在沼泽地中。一个自然的问题是，粒子物理学的标准模型，可能有一些最小的扩展，是否在沼泽地如果这个问题的答案是肯定的，我们就有麻烦了。我们根据最近沼泽地的扩张来讨论这个问题。我们证明了一个关于修改希格斯部门的不去定理。此外，我们发现，QCD轴子是不相容的，除非一些复杂的可能性被考虑到最近的沼泽地的布局。我们讨论了这一结果的CP对称性自发破缺的影响。我们评论了动力学超对称破缺以及势的多值性问题。我们还提出了一个改进的de Sitter沼泽地猜想。
A low-energy effective theory is said to be in the swampland if it does not have any consistent UV completion inside a theory of quantum gravity. The natural question is if the standard model of particle physics, possibly with some minimal extensions, are in the swampland—we are in trouble if the answer to this question is yes. We discuss this question in view of the recent swampland conjectures. We prove a no-go theorem concerning the modification of the Higgs sector. Moreover, we find that QCD axion is incompatible with the recent swampland conjectures, unless some sophisticated possibilities are considered. We discuss the implications of this result for spontaneous breaking of CP symmetry. We comment on dynamical supersymmetry breaking as well as the issue of multi-valuedness of the potential. We also propose a refinement of the de Sitter swampland conjecture.
