标题： Improved Bounds and Global Fit of Flavor-Violating Charged Lepton Yukawa Couplings post LHC

摘要： 希格斯与带电轻子的耦合是一种重要的测量方法，不仅有助于理解标准模型（SM），还能帮助研究超出标准模型（BSM）的物理。 在这项工作中，我们更新了希格斯与带电轻子的味破坏（FV）耦合的限制。 我们发现这些耦合大小的限制可能在$\sim \mathcal{O}(10^{-3}) - \mathcal{O}(10^{-6})$范围内。 实际上，LHC的直接约束比从$\tau$-$\mu$和$\tau$-$e$领域的稀有衰变间接推断出的约束强得多。 我们还将这些限制匹配到标准模型的有效场论（SMEFT），并找到了新物理（NP）尺度的下限。 我们发现新物理的尺度在$\sim \mathcal{O}(10) - \mathcal{O}(100)$TeV 范围内。 我们还提出了未来一些即将进行的实验的预测。 我们发现，目前对耦合到$\mu$-$e$的限制比所有未来的预测都更强。 显示英文摘要

摘要： Higgs couplings to charged leptons form an important measurement to understand not only the Standard Model (SM), but also physics Beyond Standard Models (BSM). In this work, we update the bounds on the Flavor-Violating (FV) Higgs couplings to charged leptons. We find that the bounds on the size of the couplings could range between $\sim \mathcal{O}(10^{-3}) - \mathcal{O}(10^{-6})$. In fact, the direct constraints from LHC are much stronger than those inferred indirectly from rare decays in the $\tau$-$\mu$ and $\tau$-$e$ sector. We also match these bounds to the SM Effective Field Theory (SMEFT) and find lower limits on the scale of New Physics (NP). We find that the scale of NP ranges between $\sim \mathcal{O}(10) - \mathcal{O}(100)$ TeV. We also present future projections for some upcoming experiments. We find that the current bounds on the couplings to $\mu$-$e$ are stronger than all future projections.
