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...
متن کاملNeutron 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 ...
متن کاملThe Nucleon Electric Dipole Moment in Light-front Qcd
I present an exact relationship between the electric dipole moment and anomalous magnetic moment of the nucleon in the light-front formalism of QCD and consider its consequences.
متن کاملThe 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...
متن کاملThe Electric Dipole Moment of the W and Electron in the Standard Model
I show that the electric dipole moment of the W-boson dW vanishes to two loop order in the standard Kobayashi-Maskawa Model of CP violation. The argument is a simple generalization of that used to show the vanishing of the quark electric dipole moment. As a consequence, the electron electric dipole moment vanishes to three loop order. Including QCD corrections may give a non-vanishing result; I...
