TeV = 1.96时ppbar碰撞中双轻子衰变通道中顶对产生截面的测量

Measurement of the Top Pair Production Cross Section in the Dilepton Decay Channel in ppbar Collisions at sqrt s = 1.96 TeV

The CDF Collaboration, T. Aaltonen

摘要:

本文报道了在$\sqrt{\rm s}$ = 1.96 TeV的$\ppbar$碰撞中,用两个轻子、缺少横向能量和喷流的事例测量$\ttbar$产生的截面。使用CDF II检测器收集数据。对应于积分亮度2.8 fb $^{-1}$的数据样本的结果是:$σ_{\ttbar}$ = 6.27 $\pm$ 0.73(统计)$\pm$ 0.63(系统)$\pm$ 0.39(流明)pb。假设顶质量为175 GeV/ $c^{2}$。

英文摘要:

A measurement of the $\ttbar$ production cross section in $\ppbar$ collisions at $\sqrt{\rm s}$ = 1.96 TeV using events with two leptons, missing transverse energy, and jets is reported. The data were collected with the CDF II Detector. The result in a data sample corresponding to an integrated luminosity 2.8 fb$^{-1}$ is: $σ_{\ttbar}$ = 6.27 $\pm$ 0.73(stat) $\pm$ 0.63(syst) $\pm$ 0.39(lum) pb. for an assumed top mass of 175 GeV/$c^{2}$.
