We have developed a concept of parallel existence of the ordinary (O) and mirror (M), or shadow (Sh) worlds. E{sub 6} unification, inspired by superstring theory, restores the broken mirror parity at the scale {approx}10{sup 18} GeV. With the aim to explain the tiny cosmological constant, we consider the breakings: E{sub 6{yields}}SO(10)xU(1){sub Z}--in the O-world, and E'6{yields}SU(6)'xSU(2)'{sub {theta}-}-in the Sh-world. We assume the existence of shadow {theta}-particles and the low energy symmetry group SU(3)'{sub C}xSU(2)'{sub L}xSU(2)'{sub {theta}x}U(1)'{sub Y} in the shadow world, instead of the Standard Model. The additional non-Abelian SU(2)'{sub {theta}}group with massless gauge fields, 'thetons', has a macroscopic confinement radius 1/{Lambda}'{sub {theta}.} The assumption that {Lambda}'{sub {theta}{approx_equal}2}.3{center_dot}10{sup -3} eV explains the tiny cosmological constant given by recent astrophysical measurements. Searching for the Dark Matter (DM), it is possible to observe and study various signals of theta-particles.
