Superpropagators for explicitly broken 3D-supersymmetric theories

A systematic algorithm to derive superpropagators in the case of either exp licitly or spontaneously broken supersymmetric three-dimensional theories i s presented. We discuss how the explicit breaking terms that are introduced at tree-level induce 1-loop radiative corrections to the effective action. We also point out that the renormalisation effects and the breaking-induci ng-breaking mechanism become more immediate whenever we adopt the shifted s uperpropagators discussed in this letter.
