Title: TileGap3 corrections for ATLAS jet triggers
Author: Carmiggelt, Joris Jip
Issue Date: 2018

Abstract: In this work a correction was developed to compensate for the excess of triggered low pT jets in the TileGap3 (TG3) region of the ATLAS detector. Online leading jet pT is scaled down proportional to the jet energy fraction deposited in the TG3 detector. Systematic analysis shows that by doing so a 2.6% decrease of wrongly triggered low pT events is achieved if a 0.1% increase of high pT events failed to trigger on is tolerated. If an order 1% increase of failed high pT events is allowed, a 4.5% decrease of wrongly triggered low pT events is realised. Suggestions are made for further studies which ultimately may lead to the implementation of this correction in ATLAS jet triggers.
