Warning: a (2,2)-Supersymmetric Epidemic!
Dr. Tristan Hubsch, ITP & Howard U

Superfields in 2-dimensional (2,2)-superspacetime which are independent of (some)
half of the fermionic coordinates are discussed in a hopefully both comprehensive
and comprehensible manner. An embarrasing 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 Kaehler
manifolds with holomorphic bundles.
