More missing VEV mechanism in supersymmetric SO(10) model
Zurab Berezhiani, Zurab Tavartkiladze
The anomalous gauge symmetry which could emerge in the context of the string theories can be very useful ingredient towards builting the complete supersymmetric SO(10) mod…
Anomalous U(1) symmetry and missing doublet SU(5) model
Zurab Berezhiani, Zurab Tavartkiladze
We present the supersymmetric models which provide a simple ``all order'' solution to the doublet-triplet splitting problem through the missing doublet mechanism. The cruci…
Unified picture of the particle and sparticle masses in SUSY GUT
Zurab Berezhiani
The horizontal symmetry can greatly help in solving the flavor problems in the supersymmetric grand unification. We consider the model and show that i…
Problem of flavour in SUSY GUT and horizontal symmetry
Zurab Berezhiani
The concept of non-abelian horizontal symmetry can greatly help in understanding the fermion and sfermion flavour structures in supersymmetric grand unification. For the…
Weak Mixing Angles as Dynamical Degrees of Freedom
Alexei Anselm, Zurab Berezhiani
In an analogy to the case of axion, which converts the -angle into a dynamical degree of freedom, we are trying to imagine a situation where the quark mixing angles turn out to…
Astrophysical Implications of the Mirror World with Broken Mirror Parity
Z. G. Berezhiani
We discuss the physics of the mirror (shadow) world which is completely analogous to the visible one except that its `weak' scale is larger by one or two orders of magnitude than t…
Fermion Masses and Mixing in SUSY GUT
Zurab Berezhiani
The problem of fermion masses and mixings is discussed in the context of supersymmetric grand unification theories. Some predictive frameworks based on the , and $S…
