= Central charges in supersymmetry
{synonym}
A central charge in four-dimensional <extended supersymmetry> is a <Lorentz scalar> even generator appearing in $\{Q_\alpha^A,Q_\beta^B\}=\epsilon_{\alpha\beta}Z^{AB}$. It commutes with the displayed translation, <Lorentz algebra>, and <supercharge> generators. An added <R-symmetry> automorphism can act on the central charges.
