Abstract
Non-linear realizations provide a convenient formalism for the description of spontaneously broken symmetries [1]. Here I would like to demonstrate how this formalism can be used for a spontaneously broken supersymmetry [2]. This talk is based on a common work with S. Samuel [3], where a detailed analysis of this idea has been given. We have in mind a situation where all the supersymmetric partners are very heavy. Therefore, we assume that there is a range of energy where the contributions to the effective Lagrangian of the super-symmetry partners can be neglected. The only sign of supersymmetry will be the existence of a goldstino field and a low-energy theorem that governs the coupling of this goldstino field to all other matter-fields.
