Search for Supersymmetry in Trimuon Final States with the CMS Detector

The trimuon signature appears in leptonic decays of charginos and neutralinos and potentially has only a small SM background in comparison with other SUSY searches. This allows to perform SUSY searches without requiring cuts on missing transverse energy or the number of jets and their energies, which are prone to large uncertainties during the first year of operation. This signature also allows for a data driven efficiency and background estimation from SM signatures with fake and prompt muons.
