Description
The LHCb experiment pioneered real-time analysis (RTA) with a fully software-based trigger operating at the 40 MHz proton–proton collision rate. Leveraging a heterogeneous computing infrastructure and high-performance reconstruction algorithms, the system delivers offline-quality event reconstruction in real time. This talk presents an overview of the RTA framework and trigger strategy employed during Run 3, including real-time reconstruction, calibration and alignment, a selective persistency model, and operational experience. Emphasis is placed on the impact of RTA on physics analyses, computing efficiency, and data management. Finally, the talk discusses the challenges and prospects for LHCb Upgrade II in the HL-LHC era, where significantly increased luminosity and event complexity will require further evolution of the real-time paradigm.
