Gauge symmetry breaking from extra space S 1 / Z 2
نویسنده
چکیده
We study a mechanism of symmetry transition upon compactification of 5-dimensional field theory on S/Z2. The transition happens unless all components in a multiplet of a symmetry group have a common Z2 parity on S /Z2. This mechanism is applied to a breakdown of SU(5) gauge symmetry in grand unified theory and phenomenological implications are discussed. ∗e-mail: [email protected]

Gauge Symmetry Reduction from the Extra Space S 1 / Z 2
The study of physics beyond 4-dimensional (4D) space-time traces back to the work by Kaluza and Klein. 1) The exsitence of an extra space is essential in superstring theory 2), 3) and M-theory. 4) Recently, there is a lot of interesting research of the phenomenological and theoretical implications of an extra space with large radii based on several motivations. 5) As a feature in theories with ...
متن کاملDeconstruction of Gauge Symmetry Breaking by Discrete Symmetry and G Unification
We deconstruct the non-supersymmetric SU(5) breaking by discrete symmetry on the space-time M4×S1 and M×S/(Z2×Z ′ 2) in the Higgs mechanism deconstruction scenario. And we explain the subtle point on how to exactly match the continuum results with the latticized results on the quotient space S/Z2 and S /(Z2 ×Z ′ 2). We also propose an effective deconstruction scenario and discuss the gauge symm...
متن کاملStandard(-like) Model from an SO(12) Grand Unified Theory in six-dimensions with S-2 extra-space
We analyze a gauge-Higgs unification model which is based on a gauge theory defined on a six-dimensional spacetime with an S2 extra-space. We impose a symmetry condition for a gauge field and non-trivial boundary conditions of the S2. We provide the scheme for constructing a four-dimensional theory from the six-dimensional gauge theory under these conditions. We then construct a concrete model ...
متن کاملGauge Symmmetry and Supersymmetry Breaking by Discrete Symmetry
We study the principles of the gauge symmetry and supersymmetry breaking due to the local or global discrete symmetries on the extra space manifold. We show that the gauge symmetry breaking by Wilson line is the special case of the discrete symmetry approach where all the discrete symmetries are global and act freely on the extra space manifold. As applications, we discuss the N = 2 supersymmet...
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...
