      abstract     = {The observed matter-antimatter asymmetry in the universe
                      cannot be explained by the Standard Model (SM) of particle
                      physics. In order to resolve the matter dominance an
                      additional CP violating phenomenon is needed. A candidate
                      for physics beyond the SM is a non-vanishing Electric Dipole
                      Moment (EDM) of subatomic particles. Since permanent EDMs
                      violate parity and time reversal symmetries, they are also
                      CP violating if the CPT theorem is assumed.The JEDI (Jülich
                      Electric Dipole moment Investigations) collaboration in
                      Jülich is preparing a direct EDM measurement of protons and
                      deuterons first at the storage ring COSY (COoler
                      SYnchrotron) and later at a dedicated storage ring. In order
                      to analyse the data and to disentangle the EDM signal from
                      systematic effects spin tracking simulations are needed.
                      Therefore a model of COSY was implemented using the software
                      library Bmad. It includes the measured magnet misalignments
                      of the latest survey and a simplified description of the
                      RF-Wien Filter device that is used for the EDM measurement.
                      Simulation results regarding the invariant spin axis as well
                      as closed orbit simulations will be presented.},
