Unified Models at Intermediate Energy Scales and Kaluza-Klein Excitations

Abstract

We discuss the possibility of intermediate gauge coupling unification in unified models of string origin. Useful relations of the β-function coefficients are derived, which ensure unification of couplings when Kaluza--Klein excitations are included above the compactification scale. We apply this procedure to two models with SU(3)\times SU(3)_L\times SU(3)_R and SU(4)\times O(4) gauge symmetries.
