Track finding algorithm using the track road method for the PANDA Forward Tracker

Abstract In this study, we present an algorithm for 3D track finding in the Forward Tracker of the PANDA experiment. This tracker is based on straw tube detectors and is designed to measure the deflection of particles in the magnetic field of the PANDA dipole magnet in order to determine their momenta. The algorithm uses the track road method for selecting track candidates. The applied track model in the projection onto the bending plane in the region before, inside and after the dipole magnet gap consists of line, circle and line, respectively. In the non-bending plane, a track projection is represented by a straight line. The algorithm was tested using simulated tracks of muons and obtained results for the track finding efficiency and for the momentum resolution are presented.
