1 Grand Unified Models on S1/(Z2 × Z ′ 2) Orbifold ∗)
We suggest two grand unified models where the fifth dimensional coordinate is compactified on an S1/(Z2 × Z ′ 2) orbifold. Before showing the models, let us see the compactification of the fifth dimension. We denote the five dimensional coordinate as y, which is compactified on an S1/(Z2 × Z ′ 2) orbifold. Under the parity transformation of Z2 and Z ′ 2, which transform y → −y and y ′ → −y (y =...
متن کاملGrand Unification of Flavor by Orbifold Twisting Z2 and Z2 × Z ′ 2
Gauge coupling unification–The simplest(rank 4) GUT SU(5) classifies the 15 chiral fields in two SU(5) representations, 10 plus 5. Of course, one can introduce SU(5) singlet(s) which must be electrically neutral, and guarantees the GUT value of the weak mixing angle 3/8. The next simplest GUT is a rank 5 group SO(10). Its rank 5 subgroup SU(5)× U(1) can be a GUT group(the so-called flipped-SU(5...
متن کاملTesting Stability of M-Theory on an S/Z2 Orbifold
We analyse perturbatively, whether a flat background with vanishing G-flux in Hořava-Witten supergravity represents a vacuum state, which is stable with respect to interactions between the ten-dimensional boundaries, mediated through the D=11 supergravity bulk fields. For this, we consider fluctuations in the graviton, gravitino and 3-form around the flat background, which couple to the boundar...
متن کاملTwistfield Perturbations of Vertex Operators in the Z2-Orbifold Model
Abstract: We apply Kadanoff’s theory of marginal deformations of conformal field theories to twistfield deformations of Z2 orbifold models in K3 moduli space. These deformations lead away from the Z2 orbifold sub-moduli-space and hence help to explore conformal field theories which have not yet been understood. In particular, we calculate the deformation of the conformal dimensions of vertex op...
متن کاملThe Hosotani Mechanism in Bulk Gauge Theories with an Orbifold Extra Space S/Z2
We pursue the possibility of the scenario in which the Higgs field is identified with the extra-space component of a bulk gauge field. The space-time we take is M ⊗ S/Z2. We show that a non-trivial Z2-parity assignment allows some of the extra-space component to have radiatively induced VEV, which strongly modifies the mass spectrum and gauge symmetry of the theory, realized by oribifolding. In...
