Triggering on Hadronic Signatures with the ATLAS Detector

At the Large Hadron Collider, many important searches for new particles and Standard Model measurements probe final states with hadronic jets and missing transverse momentum. Such events are also fundamental for precision calibration. Trigger selection of hadronic events is a extremely challenging due to immense backgrounds. This presentation summarises the implementation of hadronic triggers in the ATLAS experiment, discussing how improvements during LHC Run 2 address the background challenge and improve delivery of data for physics analysis. The evolution of jet and missing transverse momentum trigger performance is illustrated.
