SU(6) Gauge Higgs Unification — •Andreas Bally¹, Andrei Angelescu¹, Florian Goertz¹, and Simone Blasi² — ¹Max Planck Institute for Nuclear Physics, Heidelberg — ²Vrije Universiteit, Brussel, Belgium

We present a minimal viable Gauge-Higgs Grand Unification scenario in warped space based on a SU(6) bulk symmetry - unifying the gauge symmetries of the SM and their breaking sector. We show how the issue of light exotic new states is eliminated by appropriately breaking the gauge symmetry on the UV and IR boundaries by either brane scalars or gauge boundary conditions. The SM fermion spectrum is naturally reproduced including Dirac neutrinos and we compute the Higgs potential at one-loop, finding easily solutions with a realistic Higgs mass. The problem of proton decay is addressed by showing that baryon number is a hidden symmetry of the model. Among the phenomenological consequences, we highlight the presence of a scalar leptoquark and a scalar singlet. The usual X,Y gauge bosons from SU(5) GUTs are found at collider accessible masses.
