abstract = {The matter-antimatter asymmetry in the universe,
unexplained by theStandard Model of elementary particle
physics, requires CP-violatingphenomena, as proposed by A.
Sakharov. Subatomic elementary particleswith Permanent
Electric Dipole Moments (EDMs) violate timereversal and
parity asymmetries, implicating CP violation if the
CPTtheorem holds. In addition, the axion or axion like
particles (ALPs),initially proposed to explain CP violation
in quantum chromodynamicsand potentially constituting dark
matter, induce an oscillating ElectricDipole Moment (EDM)
along the spin direction when coupled withgluons.The Cooler
Synchrotron COSY at Forschungszentrum Jülich
providespolarized and unpolarized protons and deuterons up
to a momentumof 3.7 GeV/c and serves as an ideal platform
for the JEDI -Collaboration (Jülich Electric Dipole moment
Investigations) to conductthe first direct measurement of
the permanent deuteron EDMby observing its influence on spin
motion. In addition to this measurementof the static EDM,
upper limits of the oscillating deuteronEDM due to Axions or
ALPs have been measured. Both effects resultin a build-up of
a vertical polarization component which can bemeasured with
a polarimeter. This presentation will describe both
thepermanent EDM and the oscillating axion-induced EDM
experiments.},
