Abstract [en]

Semichiral (2,2) sigma models with 4d target space are discussed. A novel description in (1,1) superspace allows an analysis of possible extended supersymmetries. It is argued that a manifest semichiral realization of an extra supersymmetry is only possible for hyperk\"ahler target geometry. A semichiral formulation of the SU(2)⊗U(1) WZW model is seemingly a counterexample to this. After deriving the extra supersymmetries of this model in (1,1) superspace it is shown that they cannot be lifted to transformations of semichirals in (2,2) superspace.
