In contrast to a "single particle table-top trap", an essential feature of storage ring "trap" is that $10^{10}$ or more particles can have their spins aligned in polarized beam. This nunber large enough for the beam polarization be detected externally, and fed back permit external control polarization. The level achievable spin control, though classical, not quantum mechanical, comparable one ...

A search for the electron electric dipole moment d, is carried out with two counterpropagating beams of ground-state 'Tl. The experiment employs atomic-beam magnetic resonance with separated oscillatory fields combined with laser state selection and fluorescence detection. Extensive tests were made for possible systematic effects. The result for the atomic electric dipole moment is d, =(1.6+'5....

Requiring that the baryon number of the universe be generated by anomalous elec-troweak interactions places strong constraints on the minimal supersymmetric standard model. In particular, the electric dipole moment of the neutron must be greater than 10 −27 e-cm. Improvement of the current experimental bound on the neutron's electric dipole moment by one order of magnitude would constrain the l...

We show that the gaugino and Higgsino sectors of supersymmetric theories can naturally acquire observable CP violation through radiative effects which originate from large CP-violating trilinear couplings of the Higgs bosons to the third-generation scalar quarks. These CP-violating loop effects are not attainable by evolving the supersymmetric renormalization-group equations from a higher unifi...
