The breaking of flavor democracy in the quark sector
Harald Fritzsch, Zhi-zhong Xing, Di Zhang
The democracy of quark flavors is a well-motivated flavor symmetry, but it must be properly broken in order to explain the observed quark mass spectrum and flavor mixing pattern. W…
Naturalness and Testability of TeV Seesaw Mechanisms
Zhi-zhong Xing
After outlining some popular ways to go beyond the standard model so as to generate non-zero but tiny neutrino masses, I focus on several typical seesaw mechanisms and discuss how…
Lepton Mass Hierarchy and Neutrino Oscillations
H. Fritzsch, Z. Z Xing
Starting from the symmetry of lepton flavor democracy, we propose and discuss a simple pattern for the mass generation and flavor mixing of the charged leptons and neutrinos. The t…
A Simplified Approach to Determine and the Penguin Amplitude in
C. Hamzaoui, Z. Z. Xing
The effect of inelastic final-state interactions (IFSI's) on the determination of the weak phase from the isospin triangles of is qualitatively illustrated. N…
On Measuring Violation in Neutral -meson Decays at the Resonance
H. Fritzsch, D. Wu, Z. Xing
Within the standard model we carry out an analysis of -violating observables in neutral -meson decays at the resonance. Both time-dependent and time-integrated …
