| Abstract: | It is shown that schemes of grand unification withSU(2n)4 gauge symmetry permit the embedding of the left-right symmetricSU(2) L ×SU(2) R ×U(1)×SU(3) c intermediate symmetry at relativelylow energies between 250 GeV and a few TeV] as well as allows light unification mass-scales (≦105 TeV) ifn≧3 for values of the weak angle Sin2 θ W and the strong coupling α S in the ranges 0.20≦Sin2 θ W ≦0.25, 0.10≦α S ≦0.15. |
