Seesaw Invariance of Fritzsch-like Neutrino Mass Matrices, Leptogenesis and Lepton Flavor Violation

Zhi-zhong Xing, Shun Zhou

We propose a simple ansatz for neutrino phenomenology, in which the relevant lepton mass matrices take the universal Fritzsch-like form and the seesaw relation holds under a partic…

Flavor Democracy and Type-II Seesaw Realization of Bilarge Neutrino Mixing

Werner Rodejohann, Zhi-zhong Xing

We generalize the democratic neutrino mixing Ansatz by incorporating the type-II seesaw mechanism with S(3) flavor symmetry. We find that bilarge neutrino mixing can naturally appe…

Democratic Neutrino Mixing Reexamined

Harald Fritzsch, Zhi-zhong Xing

We reexamine the democratic neutrino mixing ansatz, in which the mass matrices of charged leptons and Majorana neutrinos arise respectively from the explicit breaking of S(3)_L x S…

Universal Neutrino Mass Hierarchy and Cosmological Baryon Number Asymmetry

Zhi-zhong Xing

We conjecture that three light Majorana neutrinos and their right-handed counterparts may have a universal geometric mass hierarchy. Incorporating this phenomenological conjecture…

Radiative Generation of with the Seesaw Threshold Effect

Jian-wei Mei, Zhi-zhong Xing

We examine whether an appreciable value of the lepton flavor mixing angle at the electroweak scale can be radiatively generated from at the…

Isomeric Lepton Mass Matrices and Bi-large Neutrino Mixing

Zhi-zhong Xing, Shun Zhou

We show that there exist six parallel textures of the charged lepton and neutrino mass matrices with six vanishing entries, whose phenomenological consequences are exactly the same…
