HORIZONTAL UNIFICATION AS THE PHENOMENOLOGY OF THE THEORY OF EVERYTHING

It is shown that the extension of the standard model of electroweak in teraction and QCD, which includes spontaneously broken horizontal loca l gauge symmetry, provides a quantitatively definite phenomenological description for almost all phenomena in particle physics and modern co smology In this model, the predictions of the standard model are combi ned with a description of the mass spectrum and mixing of quarks and l eptons, and with the predictions of the neutrino mass spectrum and par ameters of an invisible axion. This model also gives a quantitatively definite physical basis for the theory of inflation, baryosynthesis, a nd dark matter of the Universe. A complex analysis of physical, cosmol ogical, and astrophysical predictions of the model singles out a narro w range of allowed values of parameters corresponding to the ''effecti ve'' mixed cold-hot version of the theory describing the formation of the structure of the Universe. The combination of experimental and ast ronomical tests of the model that ensure its unambiguous verification is indicated.
