Description
Electric dipole moments (EDMs) play a central role in searches for CP violation beyond the Standard Model.
This talk reviews activities at the COoler SYnchrotron COSY at Forschungszentrum Juelich in Germany.
A series of milestones in the preparation for electric dipole measurements
of charged hadrons in storage rings have been achieved in recent years at COSY.
These include the measurement of spin tune, reaching spin coherence times
of over 1000 seconds, operating a feedback system to control the spin precession
in storage rings and the operation of radio-frequency devices to manipulate the spin motion.
These achievements led to a first search for axion-like particles in a storage rings
and a first measurement of the deuteron's EDM. The talk discusses the main results obtained at COSY
and plans for future developments.
