New models of SU(6) grand gauge-Higgs unification

Abstract A five dimensional SU(6) grand gauge-Higgs unification compactified on S 1/Z 2 is discussed. We propose new sets of the SU(6) representations where the quarks and leptons in one generation are embedded and there is no extra massless exotic fermions absent in the Standard Model. The correct electroweak symmetry breaking pattern can be realized by introducing some adjoint fermions. We also analyze whether a viable Higgs mass can be obtained.
