Partial breaking N=4 to N=2: hypermultiplet as a Goldstone superfield
Abstract
We describe the partial breaking of supersymmetry down to supersymmetry within the non-linear realization approach. The basic Goldstone superfield associated with this breaking is shown to be the hypermultiplet superfield subjected to a non-linear generalization of the standard hypermultiplet superfield constraint. The dynamical equations implied by this constraint are identified as the manifestly worldvolume supersymmetric equations of the Type I super 5-brane in D=10. We give arguments in favour of existence of an appropriate brane extension of off-shell hypermultiplet actions in harmonic superspace. Some related problems, in particular, the issue of utilizing other supermultiplets as Goldstone ones, are shortly discussed.
