SO (11) gauge-Higgs grand unification in the Randall-Sundrum warped space is proposed. Orbifold boundary conditions and one brane scalar field reduce SO (11) to the standard model symmetry, which is further broken to SU (3) C U (1) ₄₌ by the Hosotani mechanism. In a minimal model quarks and leptons are contained in a multiplet in 32 of SO (11) in each generation. Proton decay is naturally suppressed by a conserved fermion number.
Hosotani et al. (Mon,) studied this question.
