单顶夸克产生的发现

Discovery of Single Top Quark Production

Dag Gillberg

摘要:

最近,D 0和CDF合作组基于费米实验室Tevatron对撞机在\sqrt{s} =1.96 TeV收集的2.3和3.2 fb-1 ppbar碰撞数据首次观测到了电弱单顶夸克的产生。几个多变量的技术被用来从背景中分离的单顶信号,和两个合作目前测量的单顶横截面和CKM矩阵元素|Vtb|。

英文摘要:

The first observation of electroweak single top quark production was recently reported by the the D0 and CDF collaborations based on 2.3 and 3.2 fb-1 of ppbar collision data collected at \sqrt{s}=1.96 TeV from the Fermilab Tevatron collider. Several multivariate techniques are used to separate the single top signal from backgrounds, and both collaborations present measurements of the single top cross section and the CKM matrix element |Vtb|.
