Description
An effective description for theories with spontaneous supersymmetry breaking
can be obtained by imposing constraints on superfields, both for global and
local supersymmetry. In particular, even if the supersymmetry breaking scale
is assumed to be very high, superspace methods can still be used to study
effective theories in the low energy regime, where some of the degrees of
freedom can be decoupled. I will review the main techniques that have been
developed recently in this context and I will apply them to discuss models in
which supersymmetry is broken and non-linearly realized, both in the global
and in the local case.
