Description
The LHCb upgrade achieved for Run 3 includes a groundbreaking entirely software-based trigger. The removal of the hardware trigger is not only a significant technical advancement, but also enables substantial improvements in physics sensitivity. This presentation focuses on the performance of the first stage of the real-time analysis system (HLT1) running on GPUs. The flexibility provided by the software trigger has enabled the implementation of algorithms beyond the original Technical Design Report goals, opening possibilities for novel analyses previously unattainable at LHCb. Additionally, the talk will cover real-time alignment and calibration procedures, the monitoring implementation, and machine learning models in use within HLT1.
