论文摘要
我们将理论上的约束放置在四弗里尔标准模型相互作用的主要偏差上。调用S-Matrix的分析性和部分波浪单位性，我们开发了新的分散关系，这些关系可以在尺寸六的费米子操作员上产生自旋依赖性总和规则，或者在大动量下对振幅行为的信息进行了信息。我们发现的SMEFT不平等现象的模式遵守某些大型摩托限制的理论可以诊断出新的物理学的特性。这些关系构成了新物理搜索之间的桥梁：在Belle II中发现风味的$τ$衰减将激发人们对25 TEV低于25 TEV的新物理学的搜索，因为结果将提供有关紫外线的明确信息。
We place theoretical constraints on the leading deviations to four-fermion standard model interactions. Invoking S-matrix analyticity and partial wave unitarity, we develop new dispersion relations that yield either spin-dependent sum rules on dimension-six fermionic operators or information about the amplitude's behavior at large momentum. The pattern of SMEFT inequalities we find for theories obeying certain large-momentum constraints enables a diagnosis of properties of emerging new physics. These relations form a bridge between new physics searches: discovery of flavor-violating $τ$ decays at Belle II would motivate the search for flavor-conserving new physics below 25 TeV, as the results would provide definitive information about the UV.
