Softness of Scherk-Schwarz Supersymmetry Breaking
We investigate how the mass correction appears in 5-D with Scherk-Schwarz compactification and clarify whether the KK regularization is reliable method or not. In the extremely sharp cutoff limit of the 5-D regulator which preserves 5-D Lorentz invariance, we prove that the one loop correction to the mass does not depend on the ultraviolet physics for the Scherk-Schwarz breaking of supersymmetr...
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 کاملScherk - Schwarz Supersymmetry Breaking with Radion Stabilization
We study the issue of radion stabilization within five-dimensional supersymmetric theories compactified on the orbifold S 1 /Z 2. We break supersymmetry by the Scherk-Schwarz mechanism and explain its implementation in the off-shell formulation of five dimensional supergravity in terms of the tensor and linear compensator multiplets. We show that radion stabilization may be achieved by radiativ...
متن کاملRadiative Scherk-Schwarz supersymmetry
We analyze the Scherk-Schwarz (SS) supersymmetry breaking in brane-world five dimensional theories compactified on the orbifold S 1 /Z 2. The SS breaking parameter is undetermined at the tree-level (no-scale supergravity) and can be interpreted as the Hosotani vacuum expectation value corresponding to the U (1) R group in five dimensional N = 2 (ungauged) supergravity. We show that the SS break...
متن کاملOn string models with Scherk–Schwarz supersymmetry breaking
We construct a general class of chiral four-dimensional string models with Scherk–Schwarz supersymmetry breaking, involving freely acting orbifolds. The basic ingredient is to combine an ordinary supersymmetry-preserving ZN projection with a supersymmetry-breaking projection ZM acting freely on a subspace of the internal manifold. A crucial condition is that any generator of the full orbifold g...
