abstract = {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.},
