Tevatron上顶夸克对产生的截面

Top quark pair production cross section at Tevatron

V. Shary

摘要:

本文综述了最近在\sqrt{s} =1.96 TeV质子-反质子碰撞中,在轻子+喷流和双轻子末态中测量的顶反顶夸克对产生截面.这些测量是基于费米实验室Tevatron对撞机D 0和CDF实验收集的1 - 2.8 fb^{-1}数据。测量的截面的精度接近8%,并发现与标准模型预测兼容。对电荷希格斯粒子搜寻和顶夸克质量测量的截面测量的解释也进行了讨论。

英文摘要:

An overview of the recent measurements of the top antitop quark pair production cross section in proton antiproton collisions at \sqrt{s}=1.96 TeV in lepton + jets and dilepton final states is presented. These measurements are based on 1 -- 2.8 fb^{-1} of data collected with the D0 and CDF experiments at the Fermilab Tevatron collider. The cross section is measured with a precision close to 8% and found to be compatible with the standard model prediction. Interpretations of the cross-section measurements for charge higgs search and for top quark mass measurement are also discussed.
