We construct supersymmetric models of SO(10) unification in which the gauge symmetry is broken by orbifold compactification. We find that using boundary conditions to break the gauge symmetry down to SU(3) C⊗ SU(2) L ⊗U(1) Y⊗U(1) X without leaving unwanted massless states requires at least two extra dimensions, motivating us to work with 6D orbifolds. SO(10) is broken by two operations, each of which induces gauge breaking to either the Georgi-Glashow, Pati-Salam, or flipped SU(5)⊗U(1) subgroups; assigning different unbroken subgroups to the two operations leaves only the-standard model gauge group and U(1) X unbroken. The models we build employ extra-dimensional mechanisms for naturally realizing doublet-triplet splitting, suppressing proton decay, and avoiding unwanted grand-unified fermion mass relations. We find some tension between being free of anomalies of the 6D bulk, accommodating a simple mechanism for generating right-handed neutrino masses, and preserving the precise prediction of the weak mixing angle. © 2002 The American Physical Society.
