Description

The Hough transform is a pattern recognition technique well suited for identifying charged particle trajectories, which is used in several high-energy and heavy-ion physics experiments. The CMS experiment currently uses a combinatorial track-following method for both proton and heavy-ion collisions. In this poster we explore the possibility of using the Hough transform method in heavy ions. Such a method may improve the timing of the track reconstruction, particular for tracks with large impact parameter with respect to the primary vertex.
