A Model with Grand Unification Scale of 1019 GeV
Sandip Pakvasa, Hirotaka Sugawara · Progress of Theoretical Physics · 1986
A novel way of implementing generation symmetry before grand unification in which the unification scale can be as high as 1019 GeV, is proposed. The consequences of the simplest model of this kind, corresponding to a low energy gauge group SU(2)L×SU(2)R×SU(3)C×SU(4)G, are worked out. There are striking signatures in PP collisions from production and decay of integer charged fourth generation quarks.
