Softness of Scherk-Schwarz Supersymmetry Breaking

arXiv:hep-th/0109101 · doi:10.1103/PhysRevD.65.105021

Abstract

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 supersymmetry. This is a unique property of Scherk-Schwarz breaking which is given by the boundary condition.
