Measurements of top-quark pair and single top total cross sections, and in-situ systematic constraints

Olga Bessidskaia Bylund

摘要:

以高精度测量顶夸克对产生和单顶过程的总截面可以检验标准模型的预测,并可以更好地理解顶夸克质量、电弱耦合、轻子普适性和质子部分子分布函数等性质。本文概述了大型强子对撞机上ATLAS和CMS实验的一些最新测量结果。实验方法给予特别关注,特别是轻子隔离效率的测定在ATLAS双轻子测量顶夸克对的生产。

英文摘要:

Measuring the total cross sections of top-quark pair production and single top processes at high precision tests the predictions of the Standard Model and can bring better understanding of properties such as the top-quark mass, electroweak couplings, lepton universality and proton parton distribution functions. Some of the recent measurements by the ATLAS and CMS experiments at the Large Hadron Collider are outlined in this document. Experimental methods are given particular attention, particularly the determination of lepton isolation efficiencies in the ATLAS dilepton measurement of top-quark pair production.
