Neutron EDM in Four Generation Standard Model
A fourth generation of quarks may provide sufficient CP violation for the baryon asymmetry of the Universe. We estimate the neutron electric dipole moment in the presence of the fourth generation, and find it would be dominated by the strange quark chromoelectric dipole moment, assuming it does not get wiped out by a Peccei-Quinn symmetry. With three loop analytical expression, 500 GeV heavy qu...
متن کاملNeutron 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 کاملElectric dipole moment constraints on minimal electroweak baryogenesis
We study the simplest generic extension of the standard model which allows for conventional electroweak baryogenesis, through the addition of dimension-six operators in the Higgs sector. At least one such operator is required to be CP-odd, and we study the constraints on such a minimal setup, and related scenarios with minimal flavor violation, from the null results of searches for electric dip...
