ABOUT THESES
The theses collection aims to cover as well as possible all theses in particle physics and its related fields.
The collection starts with the thesis of Feynman, defended in 1942, and covers now alltogether more than 3000 theses. Most of the documents are held as hard copies, theses from later years are available electronically. (Note also that many theses are not physically held by the CERN Library.)

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 [...]
