论文摘要
除了在Muon $ G-2 $，$ r_ {K^{（*）}} $和$ r_ {d^{（*）} $ observables中的$ r_ {k^{（*）}} $中看到的长期异常外，CDF协作在$ W $ boson质量中发现了另一个重要一个。这些异常可能会在基本层面上交织在一起，并具有单一的新物理解释。在本文中，我们对这些异常提出了一个大致相等质量的标量leptoquarks的同时解决方案 - 一种弱的$ s_1 $，另一个是一个弱三重$ s_3 $ - 通过Higgs Portal混合。该解决方案只有几个新的耦合和TEV尺度的Leptokarks，使该解决方案可在LHC上测试。我们从当前的LHC数据中放置了该设置中的Leptoquark质量和上限，并假设所有新的耦合均在扰动极限之内。
In addition to the long-standing anomalies seen in the muon $g-2$, $R_{K^{(*)}}$, and $R_{D^{(*)}}$ observables by various independent experiments, the CDF Collaboration has found another significant one in the $W$-boson mass. These anomalies might be intertwined at a fundamental level and have a single new-physics explanation. In this paper, we present a simultaneous solution to these anomalies with two scalar leptoquarks of roughly equal mass -- one weak-singlet $S_1$ and the other a weak-triplet $S_3$ -- which mix through a Higgs portal. The solution has only a few new couplings and TeV-scale leptoquarks, making the solution testable at the LHC. We put a lower and upper bound on the leptoquark masses in this setup from the current LHC data and the assumption that all new couplings are within the perturbative limit.
