Sumario: | The Large Hadron Collider (LHC) Run 2 data taking period is coming to its end this year (2018). With the upcoming Long Shutdown 2 that will last till the end of 2020 we enter the upgrade era for the LHC based experiments. The LHCb experiment is going for a major upgrade (called LHCb Upgrade I) that practically affects all hardware components of the experimental setup as well as the DAQ and trigger. The LHCb event reconstruction procedure needs to face the challenge of fulfilling extremely tight time constraints imposed by a fully software trigger system running at the frequency of 30 MHz what corresponds to the inelastic event rate. At the same time this real time system must ensure the high level of physics performance needed by the LHCb scientific programme. This challenge requires rethinking and optimizing the logic of the event reconstruction algorithms, exploiting to the best the detectors properties and adopting out-of-the-box innovative ideas. |
