Tevatron上的顶夸克和电弱测量

Top quark and Electroweak measurements at the Tevatron

L. Cerrito

摘要:

本文介绍了最近在Tevatron上对t-tbar和单顶产生截面、顶夸克质量和宽度、顶对自旋关联和前后不对称性的初步测量结果。在电弱部分,我们给出了W玻色子宽度的Tevatron平均值,以及W和Z的前后不对称性和WZ,ZZ双玻色子产生截面的初步测量。所有测量都是基于比以前使用的更大量的碰撞数据,并且与标准模型一致。

英文摘要:

We present recent preliminary measurements at the Tevatron of t-tbar and single top production cross section, top quark mass and width, top pair spin correlations and forward-backward asymmetry. In the electroweak sector, we present the Tevatron average of the W boson width, and preliminary measurements of the W and Z forward-backward asymmetries and WZ, ZZ diboson production cross sections. All measurements are based on larger amount of collision data than previously used and are in agreement with the standard model.
