Models of Scherk-Schwarz Symmetry Breaking in 5D: Classification and Calculability
نویسندگان
چکیده
The form of the most general orbifold breaking of gauge, global and supersymmetries with a single extra dimension is given. In certain theories the Higgs boson mass is ultraviolet finite due to an unbroken local supersymmetry, which is explicitly exhibited. We construct: a 1 parameter SU(3)×SU(2)×U(1) theory with 1 bulk Higgs hypermultiplet, a 2 parameter SU(3)×SU(2)×U(1) theory with 2 bulk Higgs hypermultiplets, and a 2 parameter SU(5) → SU(3) × SU(2) × U(1) theory with 2 bulk Higgs hypermultiplets, and demonstrate that these theories are unique. We compute the Higgs mass and compactification scale in the SU(3)× SU(2)× U(1) theory with 1 bulk Higgs hypermultiplet.

5D orbifold has two attractive features: quasi-localized matter fields can naturally reproduce hierarchical Yukawa coupling, while supersymmetry breaking is inherently built in by the Scherk-Schwarz mechanism. We examine the consequence of this quasi-localization and the Scherk-Schwarz supersymmetry breaking in low energy flavor violating processes, under the assumption that physics below the c...
متن کاملScherk-Schwarz Supersymmetry Breaking in 4D
Using the techniques of dimensional deconstruction, we present 4D models that fully reproduce the physics of 5D supersymmetric theories compactified on an S/Z2 orbifold with general Scherk-Schwarz supersymmetry breaking (SSSB) boundary conditions. In contrast to previous approaches, our deconstruction involves only soft supersymmetry breaking. Deconstruction preserves many of the attractive fea...
متن کاملOn the Unification of Higgs-Nambu Goldstone Boson in the Formation of Near-brane Exotic Scalar via Scherk-Shwarz Breaking in 5-Dimensional SU(6) Symmetry
The 5D Scherk-Schwarz breaking with orbifold S/Z2 in SU(6) symmetry under special condition leads to a dimensional deconstruction without gauge symmetry breaking where SU(6) Little Higgs-like scalars show up either as weakly-coupled or strongly-coupled. The latest, together with the broken fifth component of 5D gauge boson, composes Coleman-Weinberg potential which can be generalized by substit...
متن کاملSupersymmetry breaking in a warped slice with Majorana-type masses
We study the five-dimensional (5D) supergravity compactified on an orbifold S/Z2, where the U(1)R symmetry is gauged by the graviphoton with Z2-even coupling. In contrast to the case of gauging with Z2-odd coupling, this class of models has Majoranatype masses and allows the Scherk-Schwarz (SS) twist even in the warped spacetime. Starting from the off-shell formulation, we show that the supersy...
متن کاملHD - THEP - 05 - 06 31 March 2005 Radius Stabilization by Two - Loop Casimir Energy
It is well known that the Casimir energy of bulk fields induces a non-trivial potential for the compactification radius of higher-dimensional field theories. On dimensional grounds, the 1-loop potential is ∼ 1/R 4. Since the 5d gauge coupling constant g 2 has the dimension of length, the two-loop correction is ∼ g 2 /R 5. The interplay of these two terms leads, under very general circumstances ...
