Muon detection based on a hadronic calorimeter

The ATLAS Tile hadronic calorimeter (TileCal) provides highly-segmented energy measurements of incoming particles. The information from TileCal´s last segmentation layer can assist in muon tagging and it is being considered for a future upgrade of the level-one trigger to reject triggers due to radiation background effects in the barrel region. A muon receiver for the TileCal muon signals is being designed in order to interface with the ATLAS level-one trigger. This paper addresses the preliminary studies concerning the muon discrimination capability for the muon receiver. Monte Carlo simulations for single muons from the interaction point were used to study the effectiveness of hadronic calorimeter information for muon detection.
