W Mass as a Calibration of the Jet Energy Scale at ATLAS

Top pairs will be copiously produced at the LHC, at a rate of roughly one per second at a luminosity of 10^{33} cm^{−2}s^{−1}. These events have low background and produce large numbers of jets via the hadronic decay of the W’s which may be used to calibrate the jet energy scale and resolution. We also consider the determination of the jet energy scale and the resolution through the hadronic W decays, where W boson originates from the Higgs decay produced via vector boson fusion. As this channel is one of the discovery channels and is expected to be a few orders of magnitude less than that of the top pairs, this study is intended to be purely Monte Carlo-based.
