在Tevatron对撞机上观测到单顶夸克的产生

Observation of Single Top Quark Production at the Tevatron Collider

A. P. Heinson

摘要:

2009年3月4日,DZero和CDF在费米实验室的Tevatron对撞机上合作,向《物理评论快报》(Physical Review Letters)提交了论文,宣布观测到了单顶夸克的产生。这篇综述文章描述了两个合作独立进行的成功搜索,让读者看到导致同时发现的相似性和差异。这两个合作测量的截面σ(ppbar->tb+X,tqb+X)与标准模型预测的5.0标准差显著性一致,并设置了夸克混合矩阵元|V_tb|的下限,而没有假设三代夸克的矩阵酉性。

英文摘要:

On March 4, 2009, the DZero and CDF collaborations at Fermilab's Tevatron Collider submitted papers to Physical Review Letters announcing observation of single top quark production. This review paper describes the successful searches carried out independently by the two collaborations, allowing the reader to see the similarities and differences that led to the simultaneous discoveries. Both collaborations measured a cross section sigma(ppbar->tb+X,tqb+X) consistent with the standard model prediction at 5.0 standard deviation significance, and set a lower limit on the quark mixing matrix element |V_tb| without assuming matrix unitarity with three quark generations.
