ATLAS中顶夸克对产生截面的早期数据

Top quark pair production Cross Section in ATLAS with early data

Babak Abi

摘要:

利用ATLAS pp碰撞早期的{\surd} s = 7 TeV的数据对顶夸克对进行了搜索.在轻子加喷流和双轻子通道中都观察到了几个候选事件。这些事件的属性进行了描述,并比较从蒙特卡罗模拟的期望。本文首次研究了轻子加喷注通道中的背景,包括QCD多喷注事件贡献的数据驱动确定。

英文摘要:

A search is performed for top quark pairs with early data of ATLAS pp collision taken at {\surd}s = 7 TeV. Several candidate events are observed, in both lepton plus jets and dilepton channels. The properties of these events are described, and compared to the expectations from Monte Carlo simulation. A first study of the backgrounds in the lepton plus jets channel is presented including a data-driven determination of the contribution of QCD multi-jet events.
