Three families of matters in SU(5) grand unified theory are derived from a single bulk multiplet of the SU(N) gauge group (N >= 9) in the framework of S-1/Z(2) orbifold models. In the case of the direct orbifold breaking down to the standard model gauge group, there are models in which bulk fields from a single multiplet and a few brane fields compose three families of quarks and leptons., Article, PHYSICAL REVIEW D. 76(3):035001 (2007)}, title = {Orbifold family unification}, volume = {76}, year = {2007} }
