| Abstract: | A set of fields for SO(2) supergravity theories is presented on which the gauge algebra closes at the linearized level. The Poincaré Lagrangian and three higher-order invariants are constructed. One of them, an extension of the Weyl Lagrangian, is manifestly invariant under chiral U(2) transformations. Several aspects of our results are discussed, like the particle content of the various Lagrangians and the ghost interactions that occur in the quantised Poincaré action. |
