Run-3 trigger performance: Early performance and challenges (high PU)
- Arantxa Ruiz Martinez (IFIC-Valencia)
The LHCb detector has undergone a large update during Long Shutdown 2 involving both subdetectors and the Trigger and Data acquisition systems. This talk will briefly cover the most important upgrades in the Trigger system and present how the inclusive radiative lines have been modernized to run optimally in the new conditions.
Emphasis will be given to:
- Evolving to a ‘hardware-less’...
The online event selection in ATLAS takes place in two stages. At the first level trigger (Level-1), hardware-based, custom electronics and information from the calorimeters and muon spectrometer are used to select events. At the second and final stage, the High Level Trigger (HLT), software-based, various object-specific algorithms as required by different analysis groups apply further...
The performance of the HLT and OMTF for displaced muons is presented. In Run3, new HLT paths designed to trigger on displaced muons have been added. In addition to the displaced standalone muon paths that were present in Run2, these new paths are designed to trigger on displaced global muons. Several improvements have also been made in the L1 trigger system to identify displaced muons. A new...
