Supercurrent
= Supercurrent
{title2=$S^\mu_\alpha$}
The supercurrent is the spinor-valued <Noether current> of rigid <supersymmetry>. Its spatial integral is a <supercharge>. Localizing the <supersymmetry> parameter produces $\partial_\mu\bar\epsilon\,S^\mu$ in the variation of the <action>; a <gravitino> coupling cancels this term and starts the <Noether gauging procedure>.
