description A measurement of the jet mass scale and jet mass resolution uncertainty for large radius jets using the full sqrt(s) = 8 TeV dataset from the ATLAS experiment is presented. Large radius jets are calibrated so that on average the reconstructed jet transverse momentum is the same as the corresponding particle­ level jet transverse momentum in simulation. The ratio of the reconstructed jet mass to the particle­level jet mass is the jet mass response. The mean response is the jet mass scale and the standard deviation of the jet mass response distribution is the jet mass resolution. In this study the uncertainty on these quantities is measured by fitting the W boson resonant peak in the large radius jet mass spectrum from lepton plus jets tt events in both data and Monte Carlo.
