ATLAS jet trigger performance in 2015 data
The ATLAS experiment at the LHC uses a two-level trigger system to select events with a predefined topology of interest for future analysis.The hadronic jet trigger is used to select several different topologies containing different types and multiplicities of hadronic jets, thus supporting many different physics searches and measurements.The hadronic jet trigger efficiency for protonproton collision data at a center-of-mass energy of 13 TeV is presented.The efficient selection of events containing hadronic jets requires the characteristics of trigger-level jets and offline jets to be very similar.A comparison of relevant characteristics demonstrates that they are in excellent agreement.
