The UChicago ATLAS group analysis effort builds on Monte Carlo and ATLAS software tools developed by our group in earlier years. We have focused on several closely related areas which we believe are appropriate for the early operation of the detector, such as measurement and calibration of the jet energy scale, measurement of gamma+jets, Z+jets and W+jets, as well as study of dijet events. We are also involved in the precision measurement of the W+/W- production charge asymmetry as a test of the detector and QCD parton distributions. Our group is also involved on searches for Higgs boson as well as physics beyond the standard model.
