论文摘要
我们在LHC实验中研究了标准模型有效场理论（SMEFT）的LHC实验中的Higgs玻色子和JET（THQ）。制定了一种策略来限制使用最新的LHC测量值对应于相关的SMEFT操作员的Wilson系数（WC）。提出了这些WC的最佳拟合值。最后，我们证明了找到这些操作员对LHC中THQ过程各种运动学观察力的影响的可行性。我们发现，对于一组最合适的WC值，可以在质量能量$ \ sqrt {s} = 13 $ tev的中心和集成的发光度选项$ {\ cal l} = $ 300 $ \ 300 $ \ rm fb^{ - 1} $ fb^$ 3000 $ fb^$ 300 $ fb^$ 300 $ fb^$ 300 $ fb^$ for sqrt {s} = 13 $ tev中，以合理的意义实现背景的过剩信号。
We study the top-quark production along with a Higgs boson and a jet (tHq) at the LHC experiment within the framework of the Standard Model Effective Field Theory (SMEFT). A strategy is developed to constrain the Wilson Coefficients (WC) corresponding to the associated SMEFT operators using the latest LHC measurements. The best-fit values of these WCs are presented. Finally, we demonstrate the feasibility of finding the effects of these operators on various kinematical observables of the tHq process at the LHC. We find that for a set of best-fitted values of the considered WCs, the excess of signal over the backgrounds can be achieved with a reasonable significance at the center of mass energy $\sqrt{s}=13$ TeV and for integrated luminosity options ${\cal L}=$300 $\rm fb^{-1}$ and 3000 $\rm fb^{-1}$.
