The matter-antimatter asymmetry in our Universe might be understood by investigatingthe EDM (Electric Dipole Moment) of elementary charged particles. A permanent EDM ofa subatomic particle violates time reversal and parity symmetry at the same time and wouldbe an indication for further CP violation than established in the SM (Standard Model). TheJEDI-Collaboration (J ̈ulich Electric Dipole moment Investigations) in J ̈ulich has performeda first direct EDM measurement with deuterons in the so-called precurser experiments atthe storage ring COSY (COoler SYnchrotron) at Forschungszentrum Jülich in Germany. Inorder to understand the measured data and to disentangle a potential EDM signal fromsystematic effects, spin tracking simulations in an accurate computer model of COSY areneeded. Therefore, a COSY model was implemented using the software library Bmad. As afirst step, the effect of the EDM on the invariant spin axis was benchmarked in an idealizedCOSY model. The results of the benchmarking procedure and the methods used to determinethe invariant spin axis are presented in this paper. |
