In the very early stages of LHC running, uncertainties in detector performance will lead to large ambiguities in jet, electron and photon energy measurements, along with inferred missing transverse energy ETmiss. However, muon detection should be quite straightforward, with the added benefit that muons can be reliably detected down to transverse energies of order 5 GeV. Supersymmetry discovery through multimuon channels has been extensively explored in the literature, but always relying on hard ETmiss cuts. Here, we quantify signal and background rates for same-sign (SS) dimuon and multimuon production at the LHC without any ETmiss cuts. The LHC, operating at s=10 TeV, should be able to discover a signal over expected background consistent with gluino pair production for mg˜≲450 (550) GeV in the SS dimuon plus ⩾4 jets state with just 0.1 (0.2) fb−1 of integrated luminosity.
