{title2=$S=\int d^4x\,[\int d^4\theta K+\int d^2\theta W+\mathrm{h.c.}]$}

A supersymmetric action is invariant under <supersymmetry> up to boundary terms. For ordinary four-dimensional <chiral superfields>, a full <superspace integration> of a real <Kähler potential> and a chiral <superspace integration> of a <superpotential> provide the two-derivative ungauged action.
