Large electric dipole moments of heavy leptons.
In many models of CP violation, the electric dipole moment (EDM) of a heavy charged or neutral lepton could be very large. In models in which the EDMs scale as the cube of the mass, as well as in vectorlike models, a 100 GeV heavy lepton can have an EDM as large as 0.01e fermi. This could dominate the electromagnetic properties of heavy leptons. The angular distribution and production cross sec...
متن کاملFlavor Physics with light quarks and leptons
The impact of rare K decays and lepton-flavor violating processes in shedding light on physics beyond the Standard Model is reviewd. To this purpose, I first recall the formulation of the Minimal Flavor Violation hypothesis –both in the quark and in the lepton sector– and then use it as guiding principle in comparing the new-physics sensitivity of different rare processes. On the phenomenologic...
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 کاملNaturalness 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 of Leptons in the Presence of Majorana Neutrinos
We calculate the two-loop diagrams that give a non-zero contribution to the electric dipole moment dl of a charged lepton l due to possible Majorana masses of neutrinos. Using the example with one generation of the Standard Model leptons and two heavy right-handed neutrinos, we demonstrate that the non-vanishing result for dl first appears in order O(mlm 2 νG 2 F ), where mν is the mass of the ...
