No Hope to Kinematically Detect the Effective Masses of Muon and Tau Neutrinos
Zhi-zhong Xing
We show that the recent WMAP data can impose a generous upper bound on the effective masses of electron, muon and tau neutrinos defined in the kinematic measurements: $<m>^2_e + <…
The LOW Solution and Two-zero Textures of the Neutrino Mass Matrix
Wan-lei Guo, Zhi-zhong Xing
As a viable alternative to the LMA solution to the solar neutrino problem, the LOW solution is confronted with two-zero textures of the neutrino mass matrix. We find ou…
Determining Strong and Weak Phases in B_d -> D^{(*)\pm} D^{(*)\mp} Decays
Zhi-zhong Xing
We show that both the weak phase βand the strong phase δ_d can be determined from the time-dependent measurement of B_d -> D^{*\pm} D^{\mp} decays, whose final states are non-CP ei…
Determining the Factorization Parameter and Strong Phase Differences in B-->D^(*)πDecays
Zhi-zhong Xing
The first observation of the color-suppressed decay mode \bar{B}^0_d --> D^(*)0 π^0 by the Belle and CLEO Collaborations makes a quantitative analysis of the isospin relations for…
Neutrinos: How Do They Mix and Violate CP ?
Harald Fritzsch, Zhi-zhong Xing
We discuss a simple model of lepton mixing and CP violation based on the flavor democracy of charge leptons and the mass degeneracy of neutrinos. A nearly bi-maximal flavor mixing…
Neutrino Mixing and Maximal CP Violation
Harald Fritzsch, Zhi-zhong Xing
We propose a phenomenological model of lepton mixing and CP violation based on the flavor democracy of charge leptons and the mass degeneracy of neutrinos. A nearly bi-maximal flav…
