Track reconstruction in CBM Up to now (Status Report):  track reconstruction based on smeared space points (no fake hits in strip detectors, no pileup in MAPS)  no tracking available in framework  no hit producer (digitizer) available in framework

Activities during tracking week: 1. Implementation of algorithms into framework: conformal mapping (track finding) polynomial approx (track and momentum fitting) Kalman filter (track fitting) ( ) 2. Implementation of hit producer into framework: Strip detector geometry ( ) MAPS ( ) 3. Launching of joint tracking activities R.Frühwirth/I.Kisel (deterministic annealing filter) G. Ososkov/O.Rogachevsky (conformal mapping+Hough transform) 4. Benchmarking of tracking/vertexing algorithms: D-meson reconstruction (track fitting in magnetic field) (other candidates: J/ψ and (multistrange) Hyperon reconstruction) common performance routines (efficiency, resolution, etc)
