2/3 Splitting in SUSY GUT -- Higgs as Goldstone Boson
Z. Berezhiani
We briefly review the GIFT (Goltstones instead of Fine Tuning) mechanism which provides a promising solution to the doublet-triplet splitting problem and some other puzzles of the…
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…
Matter Induced Neutrino Decay: New Candidate for the Solution to the Solar Neutrino Problrm
Zurab G. Berezhiani, Anna Rossi
Effects of the dense matter can induce the neutrino decay even if neutrinos are stable in vacuum. This is due to coherent interactions with matter which lead to energy level-splitt…
