Abstract :
Rigidly superconformal sigma models in higher than two dimensions are constructed. These models rely on the existence of conformal Killing spinors on the (p + 1)-dimensional worldvolume (p ⩽ 5), and homothetic conformal Killing vectors in the d-dimensional target space. In the bosonic case, substituting into the action a particular form of the target space metric admitting such Killing vectors, we obtain an action with mainfest worldvolume conformal symmetry, which describes the coupling of d − 1 scalars to a conformally flat metric on the worldvolume. We also construct gauged sigma models with worldvolume conformal supersymmetry. The models considered here are generalizations of the singleton actions on SP × S1, constructed some time ago by Nicolai and these authors.
