Neutron EDM from Electric and Chromoelectric Dipole Moments of Quarks [PDF]
Physical Review D, 2005 Using QCD sum rules, we calculate the electric dipole moment of the neutron d_n induced by all CP violating operators up to dimension five. We find that the chromoelectric dipole moments of quarks \tilde d_i, including that of the strange quark, provide ...

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 ...

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 interaction and presented analytical formulas for the matrix elements between atomic states ...

Physics Letters B, 2014 Nucleon electric dipole moments originating from strong CP-violation are being calculated by several groups using lattice QCD. We revisit the finite volume corrections to the CP-odd nucleon matrix elements of the electromagnetic current, which can be ...

Perspectives on electric dipole moments of atoms and molecules [PDF]
EPJ Web of Conferences, 2023 Searches for a permanent electric dipole moment (EDM) of a fundamental particle started with the key idea by Ramsey and Purcell of exploitation of discrete symmetries, such as parity, more than seven decades ago.
