Superfield currents of PoincaréN=1 supersymmetry

Starting from the algebraically reduced PoincaréN=1 superspace Noether-current, represented by four superfields obeying a conservation law, the question of further reductions is investigated. Each reduction is defined by a transformation of the four superfields leaving the conservation law as well as certain superfield currents built from them invariant. Two requirements for these superfield currents are stated and the corresponding equations are solved. An additional requirement related to, the uniqueness of the component currents is postulated.
