title = {Track reconstruction for the COMET Phase-II experiment with ACTS},
journal = {Journal of Instrumentation},
abstract = {An implementation of A Common Tracking Software (ACTS) toolkit for signal electron reconstruction for the COMET muon to electron conversion experiment is discussed.  The COMET experiment in J-PARC, Japan, will search for neutrinoless conversion of muons into electrons in the field of an aluminium nucleus, a lepton flavour violating process, aiming target sensitivity of 10-17.  To achieve its scientific goals, the experiment requires a reconstructed momentum resolution of lower than 150 keV/c.  For the first time by applying ACTS to signal events in the 100 MeV energy range with multiple-turn trajectories in the presence of background events, it is found that the reconstruction efficiency is around 14% with no fake reconstructed events. The implementation details, performance, and issues of ACTS in the context of COMET are presented.}
