Together with the real-time alignment and calibration of the detector, and a software infrastructure to make persistent the high-level physics objects produced during real-time processing, this redesign enabled the widespread deployment of real-time analysis during Run 2. We 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.Instruments & InstrumentationInstruments & Instrumentationperformance of high energy physics detectorstrigger concepts and systems (hardware and software)large detector-systems performancetrigger algorithmstext::journal::journal article::research article
