Pattern Recognition for the PANDA Forward Tracking System* — •Martin J. Galuska, Jifeng Hu, Wolfgang Kühn, J. Sören Lange, Yutie Liang, David Münchow, and Björn Spruck — II. Physik. Inst., JLU Gießen
The PANDA experiment is planned to start operation in 2017 as part of the future FAIR facility. PANDA is particularly suited to perform resonance scans of exclusively produced charmonium(-like) states. As it is a fixed target experiment a large fraction of final state particles will be boosted toward forward angles. The key challenges for forward tracking arise from the beam momentum dependent magnetic fields: PANDA is comprised of a barrel part with a solenoid field of Bz=2 T and a forward detector with a dipole field of B · L =2 Tm. The interference of the aforementioned magnetic fields leads to complex particle tracks making accurate matching of hits challenging. A Hough Transform alorithm for pattern recognition in the Forward Tracking System based upon a parabola track model was developed. The performance of a proof-of-concept implementation was studied with detailed PandaRoot simulations. Results for momentum resolution, efficiency and ghost rate will be discussed.
