Local Hadronic Calibration of Single Pion Data from the Combined ATLAS Testbeam of 2004

For the first time, the local hadronic calibration scheme has been applied to real data from the combined test beam of 2004. In this note, the performance of the weighting of the combined test beam data is shown in relation to Monte Carlo simulations. The performance of the local calibration scheme...

description For the first time, the local hadronic calibration scheme has been applied to real data from the combined test beam of 2004. In this note, the performance of the weighting of the combined test beam data is shown in relation to Monte Carlo simulations. The performance of the local calibration scheme when applied to simulated jets in full ATLAS set-up has also been demonstrated, and compared with the current default jet calibration, the "global" method. The local hadronic calibration achieves a calorimeter linearity within 3%, and the linearities of simulation and test beam data after weighting are in agreement. The calibration improves the resolution of simulated test beam data for beam energies larger than 8 GeV, and energies larger than 20 GeV for the data. In addition, the local hadronic calibration is shown to be a stable method for compensating the calorimeter system of ATLAS.
