%X The search for Electric Dipole Moments (EDMs) of elementary particles is  a powerful  tool  to  probe  physics  beyond  the  Standard  Model  (SM)  of Particle Physics.  Since permanent EDM violates CP symmetry, EDM measurement of fundamental particle is a potential source of CP-violation that would explain the matter-antimatter asymmetry in the universe.  Moreover, a rotating polarized beam used in EDM searches is sensitive to oscillating EDM caused by axions or axion-like particles (ALPs), the candidates for the dark matter. Storage rings make it possible to measure EDMs of charged particles by observing the effect of the EDM on the spin motion in the ring.  The Cooler Synchrotron COSY at the Forschungszentrum Juelich provides polarized protons and deuterons with momenta up to 3.7 GeV/s, which is an ideal testing ground and starting point for such an experimental program.  The analysis of the first direct (precursor) measurement of the deuteron EDM in COSY is currently ongoing.  Due to the complexity of storage rings, this study requires precision in measurements and thorough understanding of systematics.  Beyond that, the design report of the prototype EDM storage ring is the next milestone of the JEDI (Juelich Electric Dipole moment Investigations)research program. In this talk, I will present the current status of the JEDI program for measuring charged hadrons EDMs and searching for ALPs, discuss the various technical developments, and show recent results.
