摘要：

在这篇文章中，我回顾了最近的测量$p\bar p$碰撞中的顶夸克的产生在一个质量中心的能量为$\sqrt s=1.96$ ~TeV的费米实验室Tevatron对撞机运行II，由CDF和D 0合作记录。我将介绍$t\bar t$产生截面的Tevatron组合测量及其差分测量，$s$通道中产生单顶夸克的第一个证据和观测，以及$s$和$t$通道中产生单顶夸克的最终Tevatron组合。此外，我将回顾$t\bar t$事件中的前后不对称性的测量，这可以在Tevatron的$CP$不变的$p\bar p$初始状态下通过实验唯一地访问，并以$b\bar b$系统中的这种不对称性的测量作为结论。

英文摘要：

In this article, I review recent measurements of the production of the top quark in $p\bar p$ collisions at a centre-of-mass energy of $\sqrt s=1.96$~TeV in Run II of the Fermilab Tevatron Collider, recorded by the CDF and D0 Collaborations. I will present the Tevatron combination of measurements of the $t\bar t$ production cross section and its differential measurement, the first evidence for and observation of the production of single top quarks in the $s$-channel, as well the final Tevatron combination of the production of single top quarks the $s$- and $t$-channels. Furthermore, I will review the measurements of the forward-backward asymmetry in $t\bar t$ events, which can be experimentally uniquely accessed in the $CP$-invariant $p\bar p$ initial state at the Tevatron, and conclude with the measurements of this asymmetry in the $b\bar b$ system.
