Benjamin Nachman

摘要:

与喷流有关的径迹电荷的动量加权和提供了一个基本强相互作用粒子的电荷的实验处理。本文概述了在双射流和半轻子$t\bar{t}$事件中使用ATLAS探测器在$\sqrt{s}=8$ TeV的$5.8$ $\mathrm{fb}^{-1}$数据所产生的喷流电荷的研究。除了对强子化模型提供约束外,喷流电荷在测量和搜索中有许多可能的应用。研究了射流电荷的建模及其作为电荷示踪剂的性能,以建立这一可观察到的作为未来物理分析的工具。

英文摘要:

The momentum-weighted sum of the charges of tracks associated to a jet provides an experimental handle on the electric charge of fundamental strongly-interacting particles. An overview of a study of this jet charge observable for jets produced in dijet and semileptonic $t\bar{t}$ events using $5.8$ $\mathrm{fb}^{-1}$ of data with the ATLAS detector at $\sqrt{s}=8$ TeV is described here. In addition to providing a constraint on hadronization models, jet charge has many possible applications in measurements and searches. The modelling of jet charge and its performance as a charge-tagger are studied in order to establish this observable as a tool for future physics analyses.
