论文摘要
在LHC上生产与$ \ mathrm {z} $ boson（$ \ Mathrm {t} \ Mathrm {t} \ Mathrm {Z} \ Mathrm {j} $ Production）的生产是对标准模型的电动模型的相关探测器，以及可能具有新的phy-Physphysics效果的窗口的相关探针。对此过程进行差异测量的实验兴趣日益增长的兴趣需要改善现实的基准区域的理论建模。在本文中，我们介绍了一个NLO-Charate $ \ MathRM {T} \ MathRM {Z} \ MathRM {J} $计算，其中包括完整的外壳效果和自旋相关，将QCD和Electroweak辐射辐射校正结合到LO信号。显示了以三个带电的瘦素，两个喷气机和缺失的能量为特征的基准设置的集成和差分横截面。
The production of a single top quark in association with a $\mathrm{Z}$ boson ($\mathrm{t}\mathrm{Z}\mathrm{j}$ production) at the LHC is a relevant probe of the electroweak sector of the Standard Model as well as a window to possible new-physics effects. The growing experimental interest in performing differential measurements for this process demands an improved theoretical modelling in realistic fiducial regions. In this article we present an NLO-accurate $\mathrm{t}\mathrm{Z}\mathrm{j}$ calculation that includes complete off-shell effects and spin correlations, combining QCD and electroweak radiative corrections to the LO signal. Integrated and differential cross-sections are shown for a fiducial setup characterized by three charged leptons, two jets, and missing energy.
