  1. 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

  2. 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)

  3. Activities in February/March 2005: 1. Implementation of algorithms into framework: Track finding with cellular automaton, vertexing: I. Kisel, S. Gorbunov, E. Kryshen Track finding with Hough transform: J. Gläß, Track fitting, momentum reconstruction: E. Litvinenko conformal mapping+Hough transform: G. Ososkov, O.Rogachevsky 2. Production of realistic hit patterns (responsible ?): MAPS pileup (10, 25, 50, 100 min. bias events) Strip detectors with fake hits 3. Realistic geometries in GEANT (responsible?) Dipole magnet position, geometry for Alligator dipole, RICH position, thickness of Pixel (200 μm) and Strip (300 μm), 3. STS Station as Strip ? ........ 4. Cherenkov ring recognition Implementation of conformal mapping + Hough transform: E. Litvinenko Implementation of elastic net into framework: I. Kisel

  4. Activities based on tracking in 2005: 1. Reconstruction of low momentum electrons lower magnetic field, target out of magnetic field. ...: Krakow group, T. Galatyuk 2. Electron identification with RICH recognition of rings and tracks matching of rings with tracks : C. Höhne, B. Kostenko 3. Tracking of muons through absorber vector meson measurement via muon pairs: A. Kiseleva 4. D-meson reconstruction neutral D mesons, charged D-mesons, required Pixel performance: Y. Vassiliev 5. Full CBM track reconstruction Hit producer for TRD and RPC (incl. correct material): M. Kalisky (for TRD), Track matching: O.Rogachevsky, 6.
