论文摘要
我们使用标准模型（SM）有效的操作员在大型强子对撞机（LHC）处分析了与HIGG相关的单个最高生产，直到第六。我们表明，有效的操作员的存在可以显着改变育川顶级耦合的现有界限。我们使用基于剪切的和机器学习技术探测新物理学（NP）量表和操作员系数，以35.9和137和137和137（140）FB $^{ - 1} $进行集成的亮度分析事件，并探测相关SM背景的相关SM背景。从目前的数据和将来的灵敏度中获得了有助于信号的四个费米有效操作员，事实证明是至关重要的，并且在操作员系数上绑定。
We analyse the single top production in association with the Higgs at the Large Hadron Collider (LHC) using Standard Model (SM) effective operators upto dimension six. We show that the presence of effective operators can significantly alter the existing bound on the top-Higgs Yukawa coupling. We analyse events at the LHC with 35.9 and 137(140) fb$^{-1}$ integrated luminosities using both cut-based and machine learning techniques to probe new physics (NP) scale and operator coefficients addressing relevant SM background reduction. The four fermi effective operator(s) that contributes to the signal, turns out to be crucial and a bound on the operator coefficient is obtained from the present data and for future sensitivities.
