ACCELERATOR SEMINAR

Search for Permanent Electric Dipole Moments of Protons and Deuterons

Using Storage Rings

Frank Rathmann

for the JEDI Collaboration

Institut fur Kernphysik, Forchungszentrum

The Standard Model (SM) of Particle Physics is not capable to account

for the apparent matter-antimatter asymmetry of our Universe. Physics

beyond the SM is required and is searched for (//i//) employing highest

energies (e.g., at LHC), and (//ii//) striving for ultimate precision and

sensitivity (e.g. in the search for electric dipole moments (EDMs)).

Permanent EDMs of particles violate both time reversal (//T//) and parity

(//P//) invariance, and are via the //CPT//-theorem also CP-violating.

Finding and EDM would be a strong indication for physics beyond the SM,

and pushing upper limits further provides crucial tests for any

corresponding theoretical model, e.g. SUSY. Direct searches of proton

and deuteron EDMs bear the potential to reach sensitivities beyond

10-29e∙cm.

The talk will highlight recent achievements from experimental

investigations at COSY toward the search for electric dipole moments of

protons and deuterons in storage rings; it will emphasize the most

spectacular possibilities in modern science: Finding a signal for new

physics beyond the Standard Model through the detection of permanent

electric dipole moments in a storage ring.
