Goldman, T

The predictions and experimental status of the minimal SU/sub 5/ model are reviewed. Some alternative unification schemes, including those with lower unification scales, and their experimental implications are noted. The reduction in mass and coupling strength of the axion in grand unified theories is discussed along with Ramond's observation that the axion inducing (Peccei-Quinn) symmetry can suppress the mass scale of new fermion degrees of freedom down to the TeV level. The continuing unsolved problem of the fermion generations (lack of horizontal symmetry) is described. The attractive features of the SO(8) composite scenario of Ellis, Gaillard and Zumino are emphasized.
