Searches for Permanent Electric Dipole Moments - Some Recent Developments∗
Searches for permanent electric dipole moments (EDMs) of fundamental particles render the possibility to discover New Physics beyond present Standard Theory. New ideas for experiments have come up recently which may allow to lower present limits substantially or even find unambiguous effects. Such are predicted by a variety of speculative models. The identification of potential sources for CP a...

متن کاملElectric Dipole Moments in the MSSM Reloaded
We present a detailed study of the Thallium, neutron, Mercury and deuteron electric dipole moments (EDMs) in the CP-violating Minimal Supersymmetric extension of the Standard Model (MSSM). We take into account the complete set of one-loop graphs, the dominant Higgs-mediated two-loop diagrams, the complete CP-odd dimension-six Weinberg operator and the Higgs-mediated four-fermion operators. We i...
متن کاملElectric Dipole Moments of Fundamental Particles
The search for electric dipole moments (EDM) of fundamental particles started approximately fifty years with Ramsey’s search for a neutron EDM. Even though the techniques have been improved and the sensitivities has reached an unprecedented small level no EDM of a fundamental particle has been observed so far. Non-the-less EDM experiments have put strict limits and constrained the parameter spa...
متن کاملDark-Matter Electric and Magnetic Dipole Moments
We consider the consequences of a neutral dark-matter particle with a nonzero electric and/or magnetic dipole moment. Theoretical constraints, as well as constraints from direct searches, precision tests of the standard model, the cosmic microwave background and matter power spectra, and cosmic gamma rays, are included. We find that a relatively light particle with mass between an MeV and a few...
