Supersymmetric Grand Unification with a Fourth Generation?
J. E. Dubicki, C. D. Froggatt
The possibility of incorporating a chiral fourth generation into a SUSY-GUT is investigated. Precision fits to electroweak observables require us to introduce light supersymmetric…

Could there be a Fourth Generation?
C. D. Froggatt, J. E. Dubicki
We investigate the possibility of incorporating a chiral fourth generation into a GUT model. We find that in order to do so, precision fits to electroweak observables demand the in…
