2级的B-标识:D0的硅跟踪触发器

B-identification for Level 2: The Silicon Track Trigger at D0

S. Caron, D0 collaboration

摘要:

本文介绍了硅跟踪触发器(STT),已于2004年在DO实验中全面投产。STT允许已经在第二触发水平上用包含B介子的事件来丰富数据样本。STT通过在大约50微秒内提供具有大约50微米的碰撞参量分辨率的轨迹来实现这一点。本文给出了触发性能的初步结果,并提出了一种快速的b-识别算法的第二触发电平。

英文摘要:

This article describes the Silicon Track Trigger (STT) which has been fully commissioned in 2004 at the DO experiment. The STT allows to enrich already at the second trigger level the data sample with events containing B-mesons. The STT achieves this by providing within about 50 microseconds tracks with an impact parameter resolution of around 50 micrometer. The article shows preliminary results of the trigger performance and presents a fast b-identification algorithm for the second trigger level.
