Jet Production in p+p and Pb+Pb collisions from ATLAS

At the LHC, measurements of jet production cross sections is an important test of the Standard Model in a new unexplored energy region. In addition the study of jets is of great relevance to searches for new particles and new interactions as Standard Model processes represent a significant background. In this work, the results of the inclusive, dijet, multi-jet and W+jet cross sections are presented. Other properties of jets such as the jet shapes, azimuthal decorrelation in dijet events and the fraction of dijet events not containing an additional jet in the rapidity region bounded by the dijet system are also discussed. Results of dijet asymmetry observed in Pb+Pb collisions are also presented.
