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.
