Search for a Neutron Electric Dipole Moment
The possible existence of a nonzero electric dipole moment (EDM) of the neutron is of great fundamental interest in itself and directly impacts our understanding of the nature of electro-weak and strong interactions. The experimental search for this moment has the potential to reveal new sources of T and CP violation and to challenge calculations that propose extensions to the Standard Model. T...
متن کاملSearch for an electric dipole moment of the neutron
The result of a search for the electric dipole moment of the neutron is presented. A short review of past experimental work and theoretical predictions introduces a discussion of the experimental method used in, and the results obtained by, the present work. The weighted mean of three separate groups of data gives (+0.4 + 1.5) X 10 "cm for the neutron's electric dipole moment. We conclude that ...
متن کاملZeeman frequency shifts in an optical dipole trap used to search for an electric-dipole moment
We calculate the Zeeman frequency shifts due to interactions with the light in a far-off-resonance optical dipole trap. These shifts are important for potential use of such a trap to search for an atomic permanent electric-dipole moment ~EDM!. We present numerical results for Cs and Hg, as examples of paramagnetic and diamagnetic atoms. The vector and tensor light shifts are calculated for a la...
متن کاملThe Search for a Permanent Electric Dipole Moment
initiated a search for an electric dipole moment (EDM) of the neutron and obtained what was considered at the time a remarkably precise result, consistent with zero.1 Thus began a long line of ever more sensitive EDM experiments on neutrons, atoms, and molecules. Although no EDM has yet been found, the limits set have had decisive influences on elementary particle theories. Now, experiments und...
متن کاملSearch for the Electric Dipole Moment of the τ Lepton
We have searched for a CP violation signature arising from an electric dipole moment (dτ ) of the τ lepton in the e e → ττ reaction. Using an optimal observable method and 29.5 fb of data collected with the Belle detector at the KEKB collider at √ s = 10.58 GeV, we find Re(dτ ) = (1.15 ± 1.70) × 10e cm and Im(dτ ) = (−0.83 ± 0.86) × 10e cm and set the 95% confidence level limits −2.2 < Re(dτ ) ...
