在ATLAS上测量顶夸克对截面

Top quark pair cross section measurement at ATLAS

Martijn Gosselink

摘要:

在大型强子对撞机上对顶夸克对产生截面的精确测定为标准模型提供了一个有价值的检验。考虑到可获得的统计数据很高(大约每秒一个顶夸克对,光度为10^33 cm^-2 s^-1),在大型强子对撞机启动后,这种检查可以相对较快地完成。最后展望了在大型强子对撞机运行初期用ATLAS探测器测量顶夸克对总截面的前景。计算了单轻子通道和双轻子通道的截面。

英文摘要:

An accurate determination of the top quark pair production cross section at the LHC provides a valuable check of the Standard Model. Given the high statistics which will be available (about one top quark pair per second, at a luminosity of 10^33 cm^-2 s^-1), this check can be performed relatively fast after the turn on of the LHC. The prospects for measuring the total top quark pair cross section with the ATLAS detector during the initial period of LHC running will be presented here. The cross section is determined in the single lepton channel and in the dilepton channel.
