Structure of neutrino mass matrix and CP violation
We reconstruct the neutrino mass matrix in the flavor basis, using all available experimental data from neutrino oscillations. Majorana nature of neutrinos, normal mass hierarchy (ordering) and validity of the LMA MSW solution of the solar neutrino problem are assumed. We study dependences of the mass matrix elements, mαβ, on the CP violating Dirac, δ, and Majorana, ρ, σ, phases, for different ...
متن کاملNeutrino mass matrix: inverted hierarchy and CP violation
We reconstruct the neutrino mass matrix in flavor basis, in the case of inverted mass hierarchy (ordering), using all available experimental data on neutrino masses and oscillations. We analyze the dependence of the matrix elements mαβ on the CP violating Dirac, δ, and Majorana, ρ and σ, phases, for different values of the absolute mass scale. We find that the present data admit various structu...
متن کاملLEPTONIC CP VIOLATION and NEUTRINO MASS MODELS
We discuss leptonic mixing and CP violation at low and high energies, emphasizing possible connections between leptogenesis and CP violation at low energies, in the context of lepton flavour models. Furthermore we analyse weak basis invariants relevant for leptogenesis and for CP violation at low energies. These invariants have the advantage of providing a simple test of the CP properties of an...
متن کاملCP violation in neutrino mixing matrix and leptogenesis
The CP violation required in leptogenesis may have different origin, but in an effective theory they all are related to the rephasing invariant CP violating measure in the mixing matrix of the leptonic sector. We point out that the maximum amount of CP violation in some models can be estimated with our present knowledge of the neutrino mixing angles, which can help us understand the CP violatio...
متن کاملCP Violation and Lightest Neutrino Mass Effects in Thermal Leptogenesis
Effects of the lightest neutrino mass in “flavoured” leptogenesis when the CPviolation necessary for the generation of the baryon asymmetry of the Universe is due exclusively to the Dirac and/or Majorana phases in the neutrino mixing matrix U are discussed. The type I see-saw scenario with three heavy right-handed Majorana neutrinos having hierarchical spectrum is considered. The “orthogonal” p...
