论文摘要
我们描述了CMS协作在顶级夸克自旋和极化属性上获得的最新结果。最高的夸克自旋不对称既测量，既可以针对$ t $ channel中的单顶夸克产量，又是与Z玻色子联合的单顶夸克产量。此外，测量了顶部夸克 - 易夸克生产密度矩阵的自旋依赖性部分的所有独立系数，并将结果推断为高光度LHC场景。
We describe the latest results obtained by the CMS Collaboration on top quark spin and polarization properties. The top quark spin asymmetry is measured both targeting single-top quark production in the $t$-channel and single-top quark production in association with a Z boson. Additionally, all the independent coefficients of the spin-dependent part of the top quark-antiquark production density matrix are measured and the results are extrapolated to the High-Luminosity LHC scenario.
