Jet Reconstruction Performance

This section summarizes the general aspects of jet reconstruction with the ATLAS detector. General but brief descriptions of the available jet algorithms are provided, together with a discussion of the performance expectations for the various algorithm configurations in different detector regions and for different physics environments. The emphasis is on realistic estimates for the initial jet reconstruction performance, determined in the absence of experimental data. The corresponding expectations for important jet reconstruction parameters like signal linearity and uniformity, the relative energy resolution, and the jet reconstruction efficiency and purity, are presented.
