Tevatron上的顶夸克性质测量

Top quark property measurements at the Tevatron

Oleg Brandt

摘要:

我们回顾了最近通过CDF和D0实验对顶夸克性质的测量:顶夸克的质量和衰变宽度,$R=\btwb/\btwq$的比值$R=\btwb/\btwq$,\ttbar \对的总产生截面,$W$玻色子的螺旋度,$Wtb$顶点的反常耦合,由于色荷引起的$\ttbar$产生的不对称性,以及对顶夸克极化的首次研究.测量使用的数据样本高达8.7 \fb \获得的CDF和D0实验在运行II的费米实验室Tevatron $p\bar p$对撞机在一个中心的质量能量$\sqrt s=1.96 \TeV$。

英文摘要:

We review recent measurements of the properties of the top quark by the CDF and D0 experiments: the mass and decay width of the top quark, the ratio $R=\btwb/\btwq$, the total production cross section of \ttbar\ pairs, the helicity of the $W$ boson, anomalous couplings at the $Wtb$ vertex, the asymmetry of $\ttbar$ production due to the colour charge, and the first study of the top quark polarisation. The measurements are performed using data samples of up to 8.7 \fb\ acquired by the CDF and D0 experiments in Run II of the Fermilab Tevatron $p\bar p$ collider at a centre-of-mass energy of $\sqrt s=1.96 \TeV$.
