Evidence For SUSY From GUTS? Evidence For GUTS From SUSY!

We review the theoretical and experimental status of minimal grand unified theories (GUTS), contrasting the failure of minimal non-supersymmetric SU(5) with the success of the minimal supersymmetric SU(5) and minimal supersymmetric Flipped SU(5)× U(1) models. We show that a reasonable value for the universal soft supersymmetry-breaking gaugino mass, 45GeV < m1/2 < 1TeV, and a 1−σ range of the o...

Simple GUTs 1

Together with some positive features, such as the constrained hypercharge assignments , grandunification models typically have some unwelcome aspects, mostly associated with the rich and peculiarly selected matter content. I discuss some ideas which might help to interpret (part of) this apparent complexity arising in grandunification in terms of simple structures. I also point out that the con...

Mutational Activation of a Cistron Fragment.

NZYMES often consist of more amino acids than are necessary for full cataactivity. As an extreme example, papain may be degraded with aminopeptidase until only 76 of its original 180 amino acid residues remain, and yet retain full activity (HILL and SMITH 1960). Can analogous alterations of genes occur? A deletion penetrating into but not inactivating a gene was reported by CHAMPE and BENZER (1...
