摘要:

针对高能物理实验提出了一种改进的实时数据处理策略,并给出了该策略在LHCb实验中的实现。简化的事件模型不仅允许激发触发器的信号候选者如先前可用的那样被持久化,而且还允许来自事件的其他重构或原始对象的任意集合。与保存每个触发器的完整原始探测器数据的传统模型相比,这允许给定输出数据带宽的更高触发率,同时容纳包容性触发器并保留数据挖掘功能。讨论了该模型在物理范围和计算资源节省方面的收益,以及在大型强子对撞机运行3中更广泛地使用它的前景。

英文摘要:

An evolved real-time data processing strategy is proposed for high-energy physics experiments, and its implementation at the LHCb experiment is presented. The reduced event model allows not only the signal candidate firing the trigger to be persisted, as previously available, but also an arbitrary set of other reconstructed or raw objects from the event. This allows for higher trigger rates for a given output data bandwidth, when compared to the traditional model of saving the full raw detector data for each trigger, whilst accommodating inclusive triggers and preserving data mining capabilities. The gains in physics reach and savings in computing resources already made possible by the model are discussed, along with the prospects of employing it more widely for Run 3 of the Large Hadron Collider.
