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