WW/WZ -> lnuqq在Tevatron上的第一个证据

First Evidence of WW/WZ -> lnuqq at the Tevatron

Joseph Haley

摘要:

我们提出的第一个证据,从强子对撞机的WW+WZ生产与半轻子衰变。这些数据是由费米实验室Tevatron的D 0探测器记录的,对应于在sqrt(s)= 1.96 TeV的质子-反质子碰撞中获得的积分亮度的1.07逆飞秒。WW+WZ生产中观察到的截面为20.2 ± 4.5 pb,显著性为4.4标准差。

英文摘要:

We present the first evidence from a hadron collider of WW+WZ production with semi-leptonic decays. The data were recorded by the D0 detector at the Fermilab Tevatron and correspond to 1.07 inverse femtobarn of integrated luminosity obtained in proton-antiproton collisions at sqrt(s) = 1.96 TeV. The cross section observed for WW+WZ production is 20.2 +- 4.5 pb with a significance of 4.4 standard deviations.
