The Muon Electric Dipole Moment [PDF]

B Physics and CP Violation, 1997
The electric dipole moment of the muon ($d_\mu$) is evaluated in a two Higgs doublet model with a softly broken discrete symmetry. For $\tan\beta \equiv |v_2|/|v_1| \sim 1$, contributions from two loop diagrams involving the $t$ quark and the $W$ boson ...

Neutron Electric Dipole Moment from quark Chromoelectric Dipole Moment [PDF]

Proceedings of The 33rd International Symposium on Lattice Field Theory — PoS(LATTICE 2015), 2016
The connection between a regularization-independent symmetric momentum substraction (RI-$\tilde{\rm S}$MOM) and the $\overline{\rm MS}$ scheme for the quark chromo EDM operators is discussed.

The atomic electric dipole moment induced by the nuclear electric dipole moment; the magnetic moment effect [PDF]

Physical Review A, 2011
We have considered a mechanism for inducing a time-reversal violating electric dipole moment (EDM) in atoms through the interaction of a nuclear EDM (d_N) with the hyperfine interaction, the "magnetic moment effect". We have derived the operator for this

Electric dipole moment enhancement factor of thallium

Physical Review Letters, 2012
The goal of this work is to resolve the present controversy in the value of the EDM enhancement factor of Tl. We have carried out several calculations by different high-precision methods, studied previously omitted corrections, as well as tested our ...

Neutron Electric Dipole Moment at Fixed Topology [PDF]

Modern Physics Letters A, 2009
We describe the finite volume effects of CP-odd quantities, such as the neutron electric dipole moment and the anapole moment in the $\theta$-vacuum, under different topological sectors.

Droplet-model electric dipole moments [PDF]

Nuclear Physics A, 1986
Abstract We present a calculation of the macroscopic contribution to the dipole moment of a deformed (axially symmetric but reflection asymmetric) nucleus, using the droplet model. In addition to the familiar charge redistribution effect (which is worked out including a correction for the relative neutron excess (N - Z)/ A and a second correction, of

Electric dipole moments: Flavor-diagonal CP violation [PDF]

Comptes Rendus. Physique, 2012
Searches for permanent electric dipole moments of particles, nuclei, atoms and molecules offer an extraordinary discovery potential to new mechanisms of CP violation beyond those incorporated in the standard electroweak model. The electric dipole moments induced by speculative scenarios, on different physical systems, require a complementary approach ...

THE NEUTRON ELECTRIC DIPOLE MOMENT [PDF]

International Journal of Modern Physics A, 1988
We have made a systematic study of the electric dipole moment (EDM) of neutron Dn in various models of CP violation. We find that (i) in the standard KM model with 3 families, the neutron EDM is in the range 1.4 × 10−33 ≤ |Dn| ≤ 1.6 × 10−31 e.cm , (ii) the two Higgs doublet model has approximately the same value of Dn as the standard model, (iii ...

Constraining EDM and MDM lepton dimension-five interactions in the electroweak sector

Physics Letters B, 2020
We investigate dimension-five Lorentz-violating (LV) nonminimal interactions in the electroweak sector, in connection with the possible generation of electric dipole moment (EDM), weak electric dipole moment (WEDM), magnetic dipole moment (MDM) and weak ...

Constraining P and CP violation in the main decay of the neutral Sigma hyperon

Physics Letters B, 2019
On general grounds based on quantum field theory the decay amplitude for Σ0→Λγ consists of a parity conserving magnetic and a parity violating electric dipole transition moment.
