Abstract

In supersymmetric models with the run-away vacua or with the stable but non-supersymmetric ground state there exist stable field configurations which restore one half of supersymmetry and are characterized by constant positive energy density. We call these solutions "vacua" since they are stable with respect to local deformations of the fields. The energy-momentum tensor for these configurations is proportional to diag{1,- 1,- 1,0}, i.e. they break (spontaneously) the Lorentz and rotational invariances. The formal foundation for such vacua is provided by the central extension of the script N sign = 1 superalgebra with the infinite central charge.
