摘要：
We study the breaking of a supersymmetric SO(10) GUT in 6 dimensions by orbifold compactification. In 4 dimensions we obtain a N = 1 supersymmetric theory with the standard model gauge group enlarged by an additional U(1) symmetry, The 4-dimensional gauge symmetry is obtained as intersection of the Pati-Salam and the Georgi-Glashow subgroups of SO(10). which appear as unbroken subgroups in the two 5-dimensional subspaces, respectively. The doublet-triplet splitting arises as in the recently discussed SU(5) GUTs in 5 dimensions. (C) 2001 Elsevier Science B.V. All fights reserved.
