Real-time characterisation of the LHCb luminous region with fast FPGA-based reconstruction / Cordova, Giulio
For the ongoing LHC Run~3, LHCb has introduced an innovative trigger system that employs full software reconstruction of every collision event, marking the first time that an average \SI{30}{\mega\hertz} stream of LHC collision events is filtered based on offline-quality event reconstruction perform [...]
