Design and performance of the LHCb trigger and full real-time reconstruction in Run 2 of the LHC


LHCb Collaboration; Bernet, Roland; Müller, Katharina; Owen, Patrick; Serra, Nicola; Steinkamp, Olaf; Vollhardt, Achim; et al (2019). Design and performance of the LHCb trigger and full real-time reconstruction in Run 2 of the LHC. Journal of Instrumentation, 14(04):P04013.

Abstract

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 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.
