论文摘要
基于标准模型有效现场理论的框架，我们对未来颜色的测量值进行了一些全局拟合，每个拟合都包含尺寸-6运算符的子集。 Higgs和Electroweak行业的适合度改善了2020年EFT处理和实验投入的欧洲战略更新所做的一切。将重点放在未来山脉的4-弗里米亚互动上进行了新的全面拟合。对Top-Quark行业进行了专用拟合，该拟合限制了操作员和测量值与Top-Quark直接相关。还研究了仅涉及核场的一小部分CP侵略操作员。全球拟合中考虑了雪人2021讨论中建议的未来E+E+E-和MUON山脉的各种跑步场景。每个拟合的结果都根据对威尔逊系数的直接限制或希格斯的精度和electroweak有效耦合表示。
Based on the framework of Standard Model Effective Field Theory, we performed a few global fits, each containing a subset of dimension-6 operators, for the measurements that are expected at future colliders. The fit for the Higgs and electroweak sector improves what has been done for the European Strategy Update in 2020 on both EFT treatments and experimental inputs. A new comprehensive fit is performed focusing on 4-fermion interactions at future colliders. Top-quark sector is studied in a dedicated fit which restricts the operators and measurements to be directly related to top-quark. A small subset of CP-violating operators involving bosonic fields alone are also investigated. Various running scenarios for future e+e- and Muon Colliders that are suggested in the Snowmass 2021 discussion are considered in the global fits. The outcomes from each fit are expressed in terms of either direct constraint on Wilson Coefficients or precision on Higgs and electroweak effective couplings.
