Fig. 1 Data Missing mass rejected events see plots 87 -92 for each entry in the preceding Table. Case 2 ------ First three selections in Kmu2Analysis applied. 15 < PTrack < 35 cut applied. Then if ( !positron && !isEarly && fIsOneParticle && !isSegment && isRICHLikeMuon && fPTrack < 73. && muon && !isMult && isFinalBeam){ and use fIsLKr , fIsLAV etc in turn to reject photons. Good muon is defined as mm**2 < 0.01 GeV**2. Plots: iosmuLKrSel etc. Total events Good muons good/total rejected rejected LKr 160 85 0.53 LAV 218 172 0.79 IRC 31 27 0.87 SAC 12 9 0.75 SAV 29 23 0.79 NewLKr 15 14 0.93 isPhoton 372 278 0.75
Fig. 3 Data Missing mass rejected events see plots 139 -147 that correspond to the above table. A good muon missing mass peak is evident in all plots.
