Abstract
The Large Hadron Collider provides its experiments with an unprecedented amount of data that is impossible to record in full. The trigger systems of each experiment decide whether to retain the data for further analysis, on a timescale of the order of milliseconds. This talks contributes ideas for discussion of real-time decision making in particle physics (focusing on the ATLAS, CMS and LHCb experiments). It also presents physics cases requiring novel data acquisition techniques to make the most of LHC data, such as performing measurements or searches with physics objects reconstructed and analyzed directly within the trigger system.
