We investigate the maximal approximate flavor symmetry in the framework of generic minimal supersymmetric standard model. We consider the low energy effective theory of the flavor physics with all the possible operators included. Spontaneous flavor s

Cosmological Relics of the High Energy Cold Dark Matter Particle in the Universe

Autor: Li, Xue-Qian, Tao, Zhijian

Publikováno v: Commun.Theor.Phys. 34 (2000) 123-128

We demonstrate that if the universe is dominated by the massive cold dark matter, then besides the generally believed thermal distribution of the dark matter relics, there may exist some very energetic non-thermal relics of the dark matter particles

Spontaneous Family Symmetry Breaking And Fermion Mixing

Autor: Tao, Zhijian

Publikováno v: Phys.Lett.B355:518-522,1995

We propose a theory to describe fermion mixing. The theory respects the maximal abelian family symmetries which are spontaneously broken down at a large scale. We find that quark mixing can be well described in this theory. Some concrete models are c

Neutrinos with Zee-Mass Matrix in Vacuum and Matter

Autor: Smirnov, Alexei Yu., Tao, Zhijian

Publikováno v: Nucl.Phys. B426 (1994) 415-433

Neutrino mass matrix generated by the Zee (radiative) mechanism has zero (in general, small) diagonal elements and a natural hierarchy of the nondiagonal elements. It can be considered as an alternative (with strong predictive power) to the matrices
