论文摘要
标准模型有效场理论（SMEFT）提供了一个通用框架，以包括位于一定高能尺度$λ$的超越标准模型物理学的动力学。我们在SMEFT框架内研究了LHC实验的Higgs玻色子和Jet（THQ），研究了顶级生产。首先，确定相关的敏感尺寸-6 SMEFT运算符，制定了一种策略来限制与这些相关SMEFT运算符相对应的Wilson系数（WC），并使用最新的LHC测量值提供了一种互补的方式，以达到全球拟合方法。提出了这些WC的最佳拟合值。最后，我们讨论了这些运营商签名的发现潜力。我们发现，可以在LHC的THQ过程中观察到由于SMEFT效应而引起的多余效果，并具有质量能量$ \ sqrt {s} = 13 $ tev和集成的光度选项$ {\ cal l} = $ 300 $ \ 300 $ \ rm fb^{ - 1} $ fb^{ - 1} $ and 3000 $ \ rm fb fb^} $ 1}。
The Standard Model effective field theory (SMEFT) provides a general framework to include the dynamics of the beyond standard model physics residing at a certain higher energy scale $Λ$. We study the top-quark production along with a Higgs boson and a jet (tHq) at the LHC experiment within the framework of the SMEFT. First, identifying the relevant sensitive dimension-6 SMEFT operators, a strategy is developed to constrain the Wilson Coefficients (WC) corresponding to these associated SMEFT operators using the latest LHC measurements, providing a complementary way to the global-fit approach. The best-fit values of these WCs are presented. Finally, we discuss the discovery potential of the signatures of those operators. We find that a discoverable excess due to SMEFT effects can be observed in the tHq process at the LHC with the center of mass energy $\sqrt{s}=13$ TeV and integrated luminosity options ${\cal L}=$300 $\rm fb^{-1}$ and 3000 $\rm fb^{-1}$.
