Dimuon composition in ATLAS at 7 TeV
We present a determination of the π and K contributions to the invariant mass spectrum of di-muon events up to 150 GeV in collision data collected by the ATLAS experiment at √s = 7 TeV. These processes contribute to the backgrounds to searches for physics beyond the Standard Model where the signal h...
