N2 - We have developed a concept of parallel existence of the ordinary (O) and hidden (H) worlds with a superstring-inspired E6 unification, broken at the early stage of the Universe into SO(10)×U(1) - in the O-world, and SU(6)'×SU(2)' - in the H-world. As a result, we have obtained in the hidden world the low energy symmetry group GSM'×SU(2)'θ, instead of the Standard Model group GSM. The additional non-Abelian SU(2)'θ 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.
