SSP2012 - 5th International Symposium on Symmetries in Subatomic Physics

Theoretical studies are presented how the Electric Dipole Moment (EDM) of the electron in H-like ions in electric storage rings can be sensitively determined. The investigation follows the recent proposals to measure the muon EDM [1], the nuclear EDM [2] and the electron EDM in H-like Highly Charged Ions (HCI) [3] in magnetic storage rings, as well as the proposals to measure muon, proton and...

At the Cooler Synchrotron COSY a novel (P-even, T-odd) null test of time-reversal invariance to an accuracy of 10-6 is planned as an internal target transmission experiment. The parity conserving time-reversal violating observable is the total cross-section asymmetry Ay,xz. This quantity is measured using a polarized proton beam with an energy of 135 MeV and an internal tensor polarized...

The quest for the neutron electric dipole moment (nEDM) started more than fifty years ago and is still one of the most important tasks faced by experimental physicists. The reason is that a non zero value of this observable would break both parity (P) and time reversal (T) symmetries. Such symmetry violation is predicted by the Standard Model (SM) as well as by the various Standard Model...

The electric dipole moment (EDM) of an electron that implies the violation of the time-reversal symmetry has been searched from a half century ago. Francium (Fr) is one of the most promising candidates that could lead to observe a significant EDM because the electron EDM would be enhanced by being bounded in a heavier atom. Therefore, a factory of laser-cooled Fr atoms is being constructed...
