Sumario: | t The LHCb collaboration has redesigned its trigger to enable the full offline detector reconstruction to be performed in real time. Together with the real-time alignment and calibration of the detector, and a software infrastructure for persisting the high-level physics objects produced during real-time processing. This redesign enabled the widespread deployment of real-time analysis during Run 2. Furthermore, the widening of the LHCb physics program and the higher precision made possible by the large dataset collected in Run 2 prompted the development of several new techniques for precise calibration of the detector performance. We will describe the design of the Run 2 trigger and real-time reconstruction, and present data-driven performance measurements for a representative sample of LHCb's physics programme. |
