Coset Approach to the Partial Breaking of Global Supersymmetry

Abstract

AbstractWe propose a method to construct the on-shell component actions for the theories with 1/2 partial breaking of global supersymmetry within the nonlinear realization (coset) approach. In contrast with the standard superfield approach in which unbroken supersymmetry plays the leading role, we have shifted the attention to the spontaneously broken supersymmetry. It turns out that in the theories in which one half of supersymmetries is spontaneously broken, all physical fermions are just the fermions of the nonlinear realization. Moreover, the transformation properties of these fermions with respect to the broken supersymmetry are the same as in the famous Volkov-Akulov model.KeywordsPartial BreakingCoset ApproachUnbroken SupersymmetryBroken SupersymmetrySuperfield EquationsThese keywords were added by machine and not by the authors.
