= Superhelicity
{title2=$\kappa$}

For a four-dimensional $\mathcal N=1$ finite-helicity <massless supermultiplet>, one complex oscillator changes <helicity> by one-half. A lower-helicity labelling convention assigns $\kappa$ to the pair $(\kappa,\kappa+1/2)$. A symmetric midpoint convention instead uses $\kappa+1/4$; report the <helicity> pair when comparing conventions. <CPT completion of a supermultiplet> pairs $\kappa$ with $-\kappa-1/2$.
