FCNC, CP violation, and impure Majorana neutrinos
نویسنده
چکیده
The tree level diagonalization of a neutrino mass matrix with both Majorana and Dirac masses is discussed in a general context. Flavor changing neutral currents in such models are inevitable. Rephasing invariant quantities characterizing CP violation in FCNC FermionHiggs interactions are identified. At the one loop level, the mass eigenstates become of an impure Majorana type. The Possibility of a significant change of the mass spectrum for the left-handed neutrinos is explored, with an example of two species of neutrinos. Neutrino oscillations with impure Majorana neutrinos are also discussed.

CP Violation and Baryogenesis due to Heavy Majorana Neutrinos
We analyze the scenario of baryogenesis through leptogenesis induced by the out-ofequilibrium decays of heavy Majorana neutrinos and pay special attention to CP violation. Extending a recently proposed resummation formalism for two-fermion mixing to decay amplitudes, we calculate the resonant phenomenon of CP violation due to the mixing of two nearly degenerate heavy Majorana neutrinos. Solving...
متن کاملOn the CP Violation Associated with Majorana Neutrinos and Neutrinoless Double-Beta Decay
Assuming 3-ν mixing and massive Majorana neutrinos, we analyze the possibility of establishing the existence of CP-violation associated with Majorana neutrinos in the lepton sector by i) measuring of the effective Majorana mass || in neutrinoless double beta decay with a sufficient precision and ii) by measuring of, or obtaining a stringent upper limit on, the lightest neutrino mass m1.

متن کاملCP violation in the lepton sector with Majorana neutrinos
We study CP violation in the lepton sector in extended models with right-handed neutrinos, without and with left-right symmetry, and with arbitrary mass terms. We find the conditions which must be satisfied by the neutrino and charged lepton mass matrices for CP conservation. These constraints, which are independent of the choice of weak basis, are proven to be also sufficient in simple cases. ...
متن کاملSearching for the CP - Violation Associated with Majorana Neutrinos
The effective Majorana mass which determines the rate of the neutrinoless double beta ((ββ) 0ν-)decay, |< m >| , is considered in the case of three-neutrino mixing and massive Majo-rana neutrinos. Assuming a rather precise determination of the parameters characterizing the neutrino oscillation solutions of the solar and atmospheric neutrino problems has been made, we discuss the information a m...
متن کاملDo Neutrinos Violate Cp?
In trying to answer the question in the title of my talk, I have argued on ground of naturalness that leptonic CP violation is very likely to exist both in the form of the Kobayashi-Maskawa type and the Majorana type phases. The latter part of the argument has to be backed up by a general argument by Yanagida which states that neutrinos must be Majorana particles because our universe is asymmet...
