Abstract
The momentum spectrum and the polarization of charginos and neutralinos in squark decays are affected by gluon radiation in the decay process $\stackrel{\texttildelow{}}{q}\ensuremath{\rightarrow}q\stackrel{\texttildelow{}}{\ensuremath{\chi}}(g)$. We determine these corrections and study their impact on the $[q\ensuremath{\ell}]$ invariant mass distributions for leptonic $\stackrel{\texttildelow{}}{\ensuremath{\chi}}$ decays. The higher-order corrections, though small in general, can be sizeable near pronounced edges of the final-state distributions.
