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
4
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
mappingHough transform) 4. Benchmarking of
tracking/vertexing algorithms D-meson
reconstruction (track fitting in magnetic field)
? (other candidates J/? and (multistrange)
Hyperon reconstruction) common performance
routines (efficiency, resolution, etc)
