摘要：

We have developed a concept of parallel existence of the ordinary (O) and hidden (H) worlds with a superstring-inspired E-6 unification, broken at the early stage of the Universe into SO(10) x U(1) - in the O-world, and SU(6)' x SU(2)' - in the H-world. As a result, we have obtained in the hidden world the low energy symmetry group G(SM)' x SU(2)(theta)', instead of the Standard Model group G(SM). The additional non-Abelian SU(2)(theta)', group with massless gauge fields, "thetons", is responsible for the dark energy. We present a baryogenesis mechanism with the B - L asymmetry produced by the conversion of ordinary leptons into particles of the hidden sector. (C) 2010 Elsevier B.V. All rights reserved.
