Hadronic Calibration for the ATLAS Jet Trigger

The ATLAS trigger system must reduce the 40 MHz event rate delivered by the LHC to 200Hz. This is done by selecting online high pT objects. In proton-proton collisions, the main background for jets are also jets. Thus, the main difficulty for the jet trigger is to accurately measure the jet energy,...

description The ATLAS trigger system must reduce the 40 MHz event rate delivered by the LHC to 200Hz. This is done by selecting online high pT objects. In proton-proton collisions, the main background for jets are also jets. Thus, the main difficulty for the jet trigger is to accurately measure the jet energy, in order to distinguish high pT jets from low pT ones. The measurement of the jet energy scale is a complex issue, specially for non-compensating hadronic calorimeters, like the ATLAS one. This paper describes the strategies used to perform the hadronic calibration for the ATLAS jet trigger.
