In a new paper published in Physical Review D, the ATLAS Collaboration presents a search for new particles decaying into dijets, based on 60 billion trigger-level events collected during LHC Run 2.

The ATLAS trigger system operated extremely successfully during Run 1 (2009–2013) and Run 2 (2015–2018) of the LHC. It is now undergoing various upgrades in preparation for the upcoming Run-3 data-taking period, which will see a moderate increase in the rate of collisions inside the experiment.

On 22 November 2021 at 8pm CET, Dr. Heather Russell will give a live public talk on the ATLAS Youtube Channel on the "trigger", the ATLAS event selection system.
