论文摘要
Leptoquarks（LQS）在大统一理论中预测，并受到当前风味异常的良好动机。在本文中，我们研究了标量LQ对Higgs衰变和倾斜校正的影响，作为搜索它们的互补可观察物。考虑到标准模型量规组下的所有五个LQ表示形式，包括其中最通用的混合，我们计算出$ h \toγγ$，$ h \ to gg $，$ h \ tozγ$和peskin-takeuchi参数参数$ s $，$ s $，$ h \ h和$ $的效果。我们发现这些可观察到的物品取决于相同的拉格朗日参数，从而导致有趣的相关性。虽然当前的实验界限仅在模型上产生弱约束，但这些相关性可用于区分未来颜色的Colliders（ILC，CLIC，FCC-EE和FCC-HH）的不同LQ表示，我们将讨论其发现潜力。
Leptoquarks (LQs) are predicted within Grand Unified Theories and are well motivated by the current flavor anomalies. In this article we investigate the impact of scalar LQs on Higgs decays and oblique corrections as complementary observables in the search for them. Taking into account all five LQ representations under the Standard Model gauge group and including the most general mixing among them, we calculate the effects in $h\toγγ$, $h\to gg$, $h \to Z γ$ and the Peskin-Takeuchi parameters $S$, $T$ and $U$. We find that these observables depend on the same Lagrangian parameters, leading to interesting correlations among them. While the current experimental bounds only yield weak constraints on the model, these correlations can be used to distinguish different LQ representations at future colliders (ILC, CLIC, FCC-ee and FCC-hh), whose discovery potential we are going to discuss.
