Improvements to the LC Muon Tracking and Identification Software
  Evolution of the Muon-ID package originally written by R. Markeloff at NIU. The original method used a helical swimmer to extrapolate the tracks from the Interaction Point and to collect hits in all sub-detectors: the electromagnetic and hadronic calorimeters and the muon detector. The package was modified to replace the swimmer by a stepper which does account both for the effects of the magnetic field and for the losses by ionization in the material encountered by the particle. The Modified package shows a substantial improvement in the efficiency of muon identification. It was applied on bbar-b jets and the muon detection efficiency and purity was studied. Further improvement should be reached by accounting for stochastic processes via the utilization of the Kalman filter.
