Description
Since the reconstruction of muons is a powerful tool to identify interesting decay modes, the muon spectrometer is one of the major assets of the CMS experiment. It is placed outside of the calorimeters and the magnet, embedded in the iron yokes. the CMS design includes three different technologies of gaseous detectors: the Drift Tubes (DT), the Cathode Strip Chambers (CSC) and the Resistive Plate Chambers (RPC) for a redundant and complementary trigger.
