Abstract

We show that in some SU(N) type GUTs with the complementary pairs of the conjugated fermion multiplets there naturally appear the relatively light (M≪ M_GUT) vectorlike fermions which considerably modify the desert physics. In the non-SUSY case they can provide for the unification of the standard coupling constant α₁, α₂ and α_S whereas in the SUSY case they can increase the unification point up to the string unification limit and decrease α_S(M_Z) down to the value predicted from the low energy physics.
