Track Reconstruction and b-Jet Identification for the ATLAS Trigger System

High Energy Physics - Experiment 2015-06-03 v1

Abstract

A sophisticated trigger system, capable of real-time track reconstruction, is used in the ATLAS experiment to select interesting events in the proton-proton collisions at the Large Hadron Collider at CERN. A set of bb-jet triggers was activated in ATLAS for the entire 2011 data-taking campaign and successfully selected events enriched in jets arising from heavy-flavour quarks. Such triggers were demonstrated to be crucial for the selection of events with no lepton signature and a large jet multiplicity. An overview of the track reconstruction and online bb-jet selection with performance estimates from data is presented in these proceedings.
