Abstract
En 中文
We present expressions for the supercurrents generated by a generic 4D, N=1 theory of complex linear superfield Sigma. We verify that these expressions satisfy the appropriate superspace conservation equations. Furthermore, we discuss the component projection in order to derive expressions for the energy-momentum tensor, the supersymmetry current and the R-symmetry current when available. In addition, we discuss aspects of the coupling of the theory to supergravity. Specifically, we present a straightforward method to select the appropriate formulations of supergravity that one must use in order to do the coupling. This procedure is controlled by a superfield X originating from the Super-Poincare, invariance of the theory. We apply these results to examples of theories with higher derivative terms.
