本研究在SMEFT框架下利用轻子和强子电偶极矩测量约束CP破坏顶夸克相互作用，纳入完整效应链，并展示轻子与强子EDM的互补性及未来质子EDM搜索的增强潜力。
AI 中文摘要
电偶极矩（EDM）提供了超越标准模型（SM）的CP破坏相互作用的一些最灵敏的探针。在标准模型有效场论（SMEFT）框架内，我们利用当前和预期的轻子及强子EDM测量来研究对CP破坏顶夸克相互作用的约束。我们的分析纳入了相关效应的完整链条，包括单圈和双圈匹配、Barr-Zee贡献、Weinberg算符和重夸克阈值修正，以及重整化群诱导的算符混合。我们展示了轻子与强子EDM可观测量之间的强互补性，并表明未来的质子EDM搜索可显著加强对若干CP破坏顶夸克相互作用的约束。
英文摘要
Electric dipole moments (EDMs) provide some of the most sensitive probes of CP-violating interactions beyond the Standard Model (SM). Within the Standard Model Effective Field Theory (SMEFT), we investigate constraints on CP-violating top-quark interactions using current and projected leptonic and hadronic EDM measurements. Our analysis incorporates the complete chain of relevant effects, including one- and two-loop matching, Barr-Zee contributions, Weinberg operator and heavy-quark threshold corrections, and renormalization-group induced operator mixing. We demonstrate the strong complementarity between leptonic and hadronic EDM observables and show that future proton EDM searches could significantly strengthen constraints on several CP-violating top-quark interactions.
