Description
One of the task of track reconstruction for COMET Phase-I drift chamber is to fit multi-turn curling tracks. A method of Deterministic Annealing Filter and implements a global competition between hits from different turn tracks is introduced. This method assigns the detector measurements to the track assumption based on the weighted mean of fitting quality on different turns. This method is studied on the simulated tracks in the COMET drift chamber. We show that it can be a candidate to tell the hit turn number.
