Description

The reconstruction of multi-turn curling tracks on COMET Phase-I drift chamber is a challenge. 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. Studied have been done on the simulated tracks. We show that it can be a candidate to distinguish the hit turn.
