MIRROR WORLD WITH BROKEN MIRROR PARITY, E₆ UNIFICATION AND COSMOLOGY

Abstract

In the present paper we have developed a concept of parallel ordinary (O) and mirror (M) worlds. We have shown that in the case of a broken mirror parity (MP), the evolutions of fine structure constants in the O-and M-worlds are not identical. It is assumed that E 6 -unification inspired by superstring theory restores the broken MP at the scale ∼ 10 18 GeV, what unavoidably leads to the different E 6 -breakdowns at this scale: E 6 → SO(10) × U (1) Z -in the O-world, and E ′ 6 → SU (6) ′ × SU (2) ′ Z -in the M-world. Considering only asymptotically free theories, we have presented the running of all the inverse gauge constants α −1 i in the one-loop approximation. Then a 'quintessence' scenario suggested in Refs. [56][57][58][59][60][61] is discussed for our model of accelerating universe. Such a scenario is related with an axion ('acceleron') of a new gauge group SU (2) ′ Z which has a coupling constant g Z extremely growing at the scale Λ Z ∼ 10 −3 eV. *

Mirror dark matter: Cosmology, galaxy structure and direct detection

“…Such models, here labeled as generic hidden sector dark matter, have been extensively studied in the literature, especially in recent times. See [114,132,110,111,112,72,149,150,151,152,153,154,155,156,157,158] for a partial list.…”

Cosmological constant in a model with superstring-inspired E 6 unification and shadow θ-particles

“…The coefficients (slopes) b i , describing the running of the coupling constants with our choice of gauge groups and particle content, are given in Table 1 (according to Refs. [20,44,64,65]), for both O-and M-worlds.…”

Standard model and graviweak unification with (super)renormalizable gravity. Part I: Visible and invisible sectors of the universe

“…In Refs. [16][17][18] we considered the theory of the superstring-inspired E 6 unification with different types of the breaking of the E 6 symmetry in the visible and hidden worlds.…”
