Muon offline run readiness • Current status of offline reconstruction • Single muons (5-100 GeV PT) • Z • Single b (PT of b > 6, <3) • Bs J/ + Ks • Plans for March 1st and after Offline Muon Reconstruction for B-physics
Muon ID Calorimeter: ~1.5 Gev Toroid (BC): ~ 3 GeV • Muon = Object in muon system + matching GTrack • Tight: • GTrack (PT > 3) + A,BC track • GTrack (1.5 <PT < 3) + A segment • Loose: • GTrack (PT > 3) + A or BC segment • Extra loose: • GTrack (PT > 1.5) + hit coincidence Offline Muon Reconstruction for B-physics

Future plans: now - 3/1 • Improve central track matching • Implement tracking in calorimeter • Offline and L3 use same code • Priority: workable L3 tool • Fix bugs in reconstruction • Make it as fast as reasonably achievable and then some • Get it running smoothly on NT Offline Muon Reconstruction for B-physics

Future plans - First 100.000 events • Debug code using real data • Detector open - segments (B&C) • Detector closed - local tracks (~17% PT) • With inner tracker - global tracks • Check complete system • Do some physics? • Check J/ and Z cross sections? Offline Muon Reconstruction for B-physics
