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...

Scherk-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...

On 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...

Supersymmetry 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...

HD - 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 ...
