| heal.abstract | Recent calculations have shown that the unification scale in the string SU(5) X U(1)' X U(1)3 X [SU(4) X SO(10)]hidden model is of the order of 10(18) GeV. We perform a renormalization group analysis to examine whether it is possible to obtain the experimentally determined values of the low energy parameters sin2-theta(w) and alpha-3, including in our calculation the fractionally charges states having non-trivial transformation properties under the hidden SU(4) gauge group. We find that the model - in addition to the three generation multiplets and the standard model Higgses - should contain at least three (10 + 10BAR)SU(5) representations, while at least two (3,2) + (3BAR, 2) and (3, 1) + (3BAR, 1) vector-like SU(3) x SU(2) standard model representations should survive down to an intermediate scale of order 10(8) - 10(10) GeV. | en |
