On the off-shell formulation of N = 2 supergravity with tensor multiplets

Abstract

We revisit the construction of N = 2 superconformal multiplets using rheonomic superspace techniques. We apply the result to the derivation of off-shell Poincaré supersymmetric models where a tensor multiplet couples to gravity and to an arbitrary number of vector multiplets. We also analyze gaugings involving the tensor field.
