Naturalness bounds on dipole moments from new physics.
Assuming naturalness that the quantum corrections to the mass should not exceed the order of the observed mass, we derive and apply model-independent bounds on the anomalous magnetic moments and electric dipole moments of leptons and quarks due to new physics.
متن کاملElectric dipole moments as probes of new physics
We review several aspects of flavour-diagonal CP violation, focussing on the role played by the electric dipole moments (EDMs) of leptons, nucleons, atoms and molecules, which consitute the source of several stringent constraints on new CPviolating physics. We dwell specifically on the calculational aspects of applying the hadronic EDM constraints, reviewing in detail the application of QCD sum...
متن کاملNew Bounds on the String Scale from Flavor Physics
We review the very stringent lower bounds on the string scale that arise from flavor considerations in models with intersecting branes. Despite the absence of a realistic flavor structure at tree level, flavor changing interactions induce a non-trivial pattern of fermion masses and mixing angles when quantum corrections are taken into account. The resulting realistic theory of flavor allows us ...
متن کاملLimits on CP Violation from Electric Dipole Moments
Searches for a permanent electric dipole moment (EDM) provide a unique constraint on violation of CP symmetry beyond the Standard Model. Recent experiments improved the limits on EDMs of Hg and the electron. Combined with the limit on the neutron EDM and recent advances in theoretical interpretation, they set very tight constraints on CP violation in Supersymmetry. Many new experimental ideas a...
متن کاملNew constraint from Electric Dipole Moments on chargino baryogenesis in MSSM
A commonly accepted mechanism of generating baryon asymmetry in the minimal supersymmetric standard model (MSSM) depends on the CP violating relative phase between the gaugino mass and the Higgsino μ term. The direct constraint on this phase comes from the limit of electric dipole moments (EDM) of various light fermions. To avoid such a constraint, a scheme which assumes the first two generatio...
