  Correlators of gauge invariant operators provide useful information on the
dynamics, phases and spectra of a quantum field theory. In this paper, we
consider N=1 supersymmetric theories and focus our attention on the
supercurrent multiplet. We give a complete characterization of two-point
functions of operators belonging to such multiplet, like the energy-momentum
tensor and the supercurrent, and study the relations between them. We discuss
instances of weakly coupled and strongly coupled theories, in which different
symmetries, like conformal invariance and supersymmetry, may be conserved
and/or spontaneously or explicitly broken. For theories at strong coupling, we
exploit AdS/CFT techniques. We provide a holographic description of different
properties of a strongly coupled theory, including a realization of the
Goldstino mode in a simple illustrative model.
