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.},
