    ATLAS trigger system meets the challenges of Run 2

    ATLAS trigger system meets the challenges of Run 2 The trigger system is an essential component of any collider experiment as it is responsible for deciding whether or not to keep an event from a given bunch-crossing interaction for later study. During Run 2 (2015 to 2018) of the Large Hadron Collider (LHC), the trigger

    Trigger strategies for the LHCb experiment

    Trigger strategies for the LHCb experiment The LHCb experiment has finished a very successful data taking period in Run 2, collecting an additional 6 inverse femtobarns of proton-proton collisions. A significant modification to the Reconstruction and Trigger system of LHCb was implemented during the first LHC long shutdown period that both enhanced the physics goals

    CMS Trigger: Lessons from LHC Run 2

    CMS Trigger: Lessons from LHC Run 2 The CMS experiment has a two-level trigger system [1], to reduce the number of events stored from the LHC bunch crossing rate of 40 MHz to around 1 kHz. The first level (the Level-1) uses custom electronics to reduce the rate of events to 100 kHz, and the
