Description

We construct a grand unified model based on (N=1 local supersymmetry)xSU(5) (a ''SUGRA'' GUT) in which the only fundamental mass scale is O(Msub(Planck)). The model predicts sin2thetasub(W)=0.22, and has two near scales induced by gravitational effects Msub(x)approx.=Msub(Planck)/√8π, Msub(SUSY)approx.=1011 GeV. SU(2)xU(1) is broken by radiative corrections for a top quark mass in the range 30<msub(t)<130 GeV and the colour triplets of Higgs scalars are automatically superheavy. (orig.)
