  A detailed study of the same-sign muon signature within the mSUGRA model is
described. Selection criteria based on the missing transverse energy in the
events and the jet and muon transverse momenta are applied. The results
indicate that an excess of SUSY events over the Standard Model background
processes can be statistically significant for an integrated luminosity of less
than 10 fb^-1 for many benchmark points with m_1/2 up to 650 GeV/c^2.
