Description
ATLAS uses a jet reconstruction algorithm in heavy ion collisions that takes as input calorimeter towers of size 0.1x0.1 in $\Delta\eta$ x $\Delta\phi$ and iteratively determines the underlying event background. This algorithm, which is different from the standard jet reconstruction used in ATLAS, is also used in the proton-proton collisions used as reference data for the Pb+Pb and p+Pb. This poster provides details of the heavy ion jet reconstruction algorithm and its performance in p+p collisions. The calibration procedure is described in detail and cross checks using photon-jet balance are shown. The uncertainties on the jet energy scale and the jet energy resolution are described.
