Abstract
We analyze proton decay and the choice of Higgs fields in grand unified theories where the baryon number is a gauge symmetry [e.g., SU(15)]. Although Higgs effects forbid low-energy unification in the SU(15) model (within the extended survival hypothesis) as claimed by Frampton and Lee, other breaking patterns exist which allow unification at 109 GeV, as well as chiral color symmetry, quark-lepton ununified symmetry, and baryon-number symmetry breaking at the TeV scale, without any observable proton decay.
