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

A sophisticated trigger system, capable of real-time track reconstruction, is in place in the ATLAS experiment, to reject most of the events containing uninteresting background collisions while preserving as much as possible the interesting physics signals. The strategy adopted for fast reconstructi...

description A sophisticated trigger system, capable of real-time track reconstruction, is in place in the ATLAS experiment, to reject most of the events containing uninteresting background collisions while preserving as much as possible the interesting physics signals. The strategy adopted for fast reconstruction of charged tracks and in particular its application to the selection of jets from the hadronization of b-quarks is reviewed. Track reconstruction is routinely used for selection based on various physics objects while b-jet triggers are actively selecting events from the beginning of the 2011 LHC data-taking campaign.
