Running CP-violating Phases of Majorana Neutrinos
Three CP-violating phases of the 3 × 3 lepton flavor mixing matrix V , denoted as δ , ρ and σ in a useful phase convention, are entangled with one another in the one-loop renormalization-group equations. We show that δ = 90 • at the electroweak scale (Λ EW ∼ 10 2 GeV) can be radiatively generated from δ = 0 • at the seesaw scale (Λ SS ∼ 10 14 GeV) in the minimal supersymmetric standard model, p...
متن کاملDistinguishable RGE running effects between Dirac neutrinos and Majorana neutrinos with vanishing Majorana CP-violating phases
In a novel parametrization of neutrino mixing and in the approximation of τ lepton dominance, we show that the one-loop renormalization-group equations (RGEs) of Dirac neutrinos are different from those of Majorana neutrinos even if two Majorana CP-violating phases vanish. As the latter can keep vanishing from the electroweak scale to the typical seesaw scale, it makes sense to distinguish betw...
متن کاملTexture Zeros and Majorana Phases of the Neutrino Mass Matrix
We present the generic formulas to calculate the ratios of neutrino masses and the Majorana phases of CP violation from the neutrino mass matrix with two independent vanishing entries in the flavor basis where the charged lepton mass matrix is diagonal. An order-of-magnitude illustration is given for seven experimentally acceptable textures of the neutrino mass matrix, and some analytical appro...
متن کامل+ γ , Leptogenesis CP - Violating Parameters and Majorana Phases
We analyse the dependence of the rates of the LFV charged lepton decays µ → e + γ, τ → e+γ, τ → µ+γ (l i → l j +γ) and their ratios, predicted in the class of SUSY theories with seesaw mechanism of ν-mass generation and soft SUSY breaking with universal boundary conditions at the GUT scale, on the Majorana CP-violation phases in the PMNS neutrino mixing matrix and the " leptogenesis " CP-violat...
متن کاملThe effects of Majorana phases in three-generation neutrinos
Neutrino-oscillation solutions for the atmospheric neutrino anomaly and the solar neutrino deficit can determine the texture of the neutrino mass matrix according to three types of neutrino mass hierarchies as Type A: m1 ≪ m2 ≪ m3, Type B: m1 ∼ m2 ≫ m3 , and Type C: m1 ∼ m2 ∼ m3, where mi is the i-th generation neutrino absolute mass. The relative sign assignments of neutrino masses in each typ...
