Tevatron上电弱单顶夸克产生的观测

Observation of Electroweak Single Top Quark Production at the Tevatron

Enrique Palencia

摘要:

我们报告的第一个观察到的单顶夸克的生产使用ppbar碰撞数据与sqrt{s}=1.96 TeV收集的CDF II和D 0探测器在费米实验室。观察到的CDF和D 0数据的显著性均为5.0标准差,预期灵敏度分别超过5.9和等于4.5标准差。单顶生产截面与CKM矩阵元值|V_{tb}|已经被测量了。

英文摘要:

We report the first observation of single top quark production using ppbar collision data with sqrt{s}=1.96 TeV collected by the CDF II and D0 detectors at Fermilab. The significance of both the observed CDF and D0 data is 5.0 standard deviations, and the expected sensitivity is in excess of 5.9 and equal to 4.5 standard deviations, respectively. The single top production cross section and the CKM matrix element value |V_{tb}| have been measured.
