D0实验中改进的$b$夸克喷注识别

Improved $b$ quark jet identification at the D0 experiment

D0 Collaboration

摘要:

在费米实验室Tevatron $p\bar{p}$对撞机上进行的D0实验中,识别源自$b$夸克的喷流是一个重要的物理工具。本文描述了一种新的算法,设计用于选择来自$b$夸克的喷注,同时抑制来自其他夸克味和胶子的喷注造成的污染。此外,一个新的技术,系统N方法,直接从数据确定的错误识别率。

英文摘要:

The ability to identify jets which originated from $b$ quarks is an important tool of the physics program of the D0 experiment at the Fermilab Tevatron $p\bar{p}$ collider. This article describes a new algorithm designed to select jets originating from $b$ quarks while suppressing the contamination caused by jets from other quark flavors and gluons. Additionally, a new technique, the SystemN method, for determining the misidentification rate directly from data is presented.
