Neutron Electric Dipole Moment in the Minimal Supersymmetric Standard Model

Neutron electric dipole moment (EDM) due to single quark EDM and to the transition EDM is calculated in the minimal supersymmetric standard model. Assuming that the Cabibbo-Kobayashi-Maskawa matrix at the grand unification scale is the only source of CP violation, complex phases are induced in parameters of soft supersymmetry breaking at low energies. Chargino one-loop diagram is found to give ...

The electric dipole moment of the neutron in the constrained minimally supersymmetric standard model

We analyse the electric dipole moment of the neutron in the MSSM, induced by the renormalisation of the soft-susy breaking terms. We run the RGEs using twoloop expressions for gauge and Yukawa couplings and retaining family dependence. The μ and B parameters were determined by minimising the full one-loop Higgs potential, and we find that the neutron EDM lies in the range 10 < |dn| < 10 e cm. P...

Neutron Electric Dipole Moment In The Standard Model : Valence Quark

We present a complete three-loop calculation of the electric dipole moment of the u and d quarks in the Standard Model. For the d quark, more relevant for the experimentally important neutron electric dipole moment, we nd cancellations which lead to an order of magnitude suppression compared with previous estimates. The electric dipole moment (EDM) of the neutron, d n , has been subject of expe...

The Neutron Electric Dipole Moment and CP-violating Couplings in the Supersymmetric Standard Model without R-parity

We analyze the neutron electric dipole moment (EDM) in the Minimal Supersymmetric Model with explicit R-parity violating terms. The leading contribution to the EDM occurs at the 2-loop level and is dominated by the chromoelectric dipole moments of quarks, assuming there is no tree-level mixings between sleptons and Higgs bosons or between leptons and gauginos. Based on the experimental constrai...

Neutron Electric Dipole Moment Experiments

The possibility of a non-zero value for neutron EDM continues to be of central importance in physics and cosmology. A non-zero neutron EDM would be a direct evidence for time-reversal symmetry violation. It also implies CP-violation under the assumption of CPT invariance. To date, only two examples of CP-violation have been found: decays of neutral K mesons and B mesons. CP-violation is believe...
