The Belle II experiment is designed to collect 50 times more data than its predecessor. For a smooth collection of high-quality data, a robust and automated data transport and processing pipeline has been established. We describe the basic software components employed by the high level trigger. It performs a reconstruction of all events using the same algorithms as offline, classifies the events according to physics criteria, and provides monitoring information. The improved system described in this paper has been deployed successfully since 2019.

Belle II 实验中用于在线重建和过滤的软件

Belle II 实验旨在收集比其前身多 50 倍的数据。为了顺利收集高质量的数据，已经建立了强大的自动化数据传输和处理管道。我们描述了高级触发器使用的基本软件组件。它使用与离线相同的算法执行所有事件的重建，根据物理标准对事件进行分类，并提供监控信息。本文描述的改进系统自 2019 年以来已成功部署。
