Abstract
An equivalence theorem relating S-matrix elements with some external helicity \ifmmode\pm\else\textpm\fi{}(1/2 gravitinos to S-matrix elements with corresponding external Goldstinos at high energy is rigorously proven from a set of Ward identities of N=1 supergravity. A more intuitive proof is given using the functional integral formalism. Similar equivalence theorems hold in general in theories possessing gauge properties spontaneously broken by a Higgs-type mechanism.
