= Scalar superfield transformation
{title2=$\delta S=(\epsilon Q+\bar\epsilon\bar Q)S$}
With <left Grassmann derivatives>, let $Q_\alpha=\partial_\alpha-i\sigma^\mu_{\alpha\dot\beta}\bar\theta^{\dot\beta}\partial_\mu$ and $\bar Q_{\dot\alpha}=\bar\partial_{\dot\alpha}-i\theta^\beta\sigma^\mu_{\beta\dot\alpha}\partial_\mu$. Left-placed odd parameters generate $\delta\theta=\epsilon$, $\delta\bar\theta=\bar\epsilon$ and $\delta x^\mu=i\theta\sigma^\mu\bar\epsilon-i\epsilon\sigma^\mu\bar\theta$. A scalar <superfield> transforms by pullback under this <superspace> translation. The parameter-weighted variation is an even <derivation>, although each <supercharge> is odd.
