Abstract

Semichiral sigma models with a four-dimensional target space do not support extended N = (4, 4) supersymmetries off-shell [ 1 , 2 ]. We contribute towards the understanding of the non-manifest on-shell transformations in (2, 2) superspace by analyzing the extended on-shell supersymmetry of such models and find that a rather general ansatz for the additional supersymmetry (not involving central charge transformations) leads to hyperkähler geometry. We give non-trivial examples of these models.
