Electric dipole moment (EDM) studies of the charged particles at COSY-Juelich: Detector Modelling - Event generator for deuteron proton elastic scattering.

Parity (P) and time reversal symmetry (T) invariance prohibit elementary particles to have a non-zero electric dipole moment (EDM). Standard Model (SM) describes the interactions between the elementary particles, along with the small CP symmetry violation, nevertheless it is not enough to explain the existing ratio of matter and antimatter. EDM non-zero value is a direct proof of CP violation, which is a necessary condition to solve the baryon-antibaryon asymmetry in our universe. There is a necessity to measure the electric dipole moment of the light nuclei like deuterons. It should be noted, that such experiments require a very high precision. The goal for the deuteron EDM experiments at COSY-accelerator in Juelich is to achieve an EDM sensitivity of ~10-29 e*cm, which requires a spin coherence time of at least 1000 s along with the ability to measure 10 -6 radians. So far the spin coherence time of 400s has been achieved, hence the accelerator should be optimized. Prior to any new experiment the choice of the detector concept and its modeling takes place. This bachelor thesis describes the event generator code for deuteron-proton elastic scattering, which is one of the first and important steps in the detector modeling. The left-right asymmetry of elastically scattered deuterons lets us determine the deuteron beam polarization, which emerged in the COSY accelerator ring due to deuteron non-zero EDM. In order to choose the size and position of the detector as well as the duration of the experiment, it is necessary to have a real events generator. Our goal is to simulate dp elastic scatteringwith the deuteron beam kinetic energy of 270 MeV. The choice of this reaction is based on the fact, that the analyzing power at this energy is known with a good precision, which is necessary to determine the polarization. The given problem has been motivated by its usefulness for the EDM studies at COSY-Juelich.
