We discuss inflationary cosmology in a five dimensional SO(10) model compactified on S/(Z2×Z ′ 2), which yields SU(3)c×SU(2)L×U(1)Y ×U(1)X below the compactification scale. The gauge symmetry SU(5)×U(1)X is preserved on one of the fixed points, while ‘flipped’ SU(5)×U(1)X is respected on the other fixed point. Inflation is associated with U(1)X breaking, and is implemented through F-term scalar...

We present a five dimensional SO(10) model compactified on S/(Z2×Z ′ 2), which yields SU(3)c×SU(2)L×U(1)Y ×U(1)X below the compactification scale. The gauge symmetry SU(5) × U(1)X is preserved on one of the fixed points, while ‘flipped’ SU(5) × U(1)′X is respected on the other fixed point. Inflation is associated with U(1)X breaking, and is implemented through F-term scalar potentials on the tw...

We calculate the full 1-loop corrections to the low energy coupling of bulk gauge boson in a slice of AdS5 which are induced by generic 5-dimensional scalar, Dirac fermion, and vector fields with arbitrary Z2×Z ′ 2 orbifold boundary conditions. In supersymmetric limit, our results correctly reproduce the results obtained by an independent method based on 4-dimensional effective supergravity. Th...
