Abstract

We study the 6-dimensional N=2 supersymmetric grand unified theories with gauge group SU(N) and $S O (M)$ on the extra space orbifolds $T^{2} / (Z_{2})^{3}$ and $T^{2} / (Z_{2})^{4}$ , which can be broken down to the 4-dimensional N=1 supersymmetric $S U (3) \times S U (2) \times U (1)^{n - 3}$ model for the zero modes. We also study the models which have two SU(2) Higgs doublets (zero modes) from the 6-dimensional vector multiplet. We give the particle spectra, present the fields, the number of 4-dimensional supersymmetry and gauge group on the observable 3-brane or 4-brane and discuss some phenomenology for those models. Furthermore, we generalize our procedure for $(4 + m)$ -dimensional $N$ supersymmetric GUT breaking on the space-time $M^{4} \times T^{m} / (Z_{2})^{L}$ .
