= Chiral field-strength superfield
{title2=$W_\alpha$}

For a non-Abelian vector superfield, the chiral field-strength superfield is
$$
W_\alpha=-\frac18\bar D^2\left(e^{-2V}D_\alpha e^{2V}\right).
$$
It obeys $\bar D_{\dot\alpha}W_\alpha=0$ and transforms covariantly under a supergauge transformation.
