N=1 supersymmetric formulation of the field theory with the fundamental mass

The N=1 supercovariant formulation of the theory with the fundamental mass (FM) is proposed. All superfields are treated in the five-dimensional configurational space in which they satisfy the fundamental equation (FE). The Cauchy data for FE are field variables defined in the usual space-time. Their equations are derived as extremals of supercovariant functionals of action. It turns out that supercovariant functionals of action. It turns out that the latter generalise the action of material and gauge fields which are specific of the theory with FM. 7 refs
