Potentials for (p, 0) and (1, 1) supersymmetric sigma models with torsion

Using (1, 0) superfield methods, we determine the general scalar potential consistent with off-shell (p, 0) supersymmetry and (1, 1) supersymmetry in two-dimensional non-linear sigma models with torsion. We also present an extended superfield formulation of the (p, 0) models and show how the (1, 1) models can be obtained from the (1, 1)-superspace formulation of the gauged, but massless, (1, 1) sigma model
