Haploid (2, 2)-superfields in 2-dimensional space-time Original Research Article

Superfields in 2-dimensional (2,2)-superspace-time which are independent of (some) half of the fermionic coordinates are discussed in a hopefully both comprehensive and comprehensible manner. An embarrassing abundance of these simplest ‘building blocks’ makes it utterly impossible to write down the ‘most general Lagrangian’. With some ad hoc but perhaps plausible restrictions, a rather general Lagrangian is found, which exhibits many of the phenomena that have been studied recently, and harbors many more. In particular, it becomes patently obvious that the (2,2)-supersymmetric 2-dimensional field theory target space geometries (many of which are suitable for (super)string propagation) are far more general than Kähler manifolds with holomorphic bundles.
