Gluon Radiation Off Scalar Stop Particles

We present the distributions for gluon radiation off stop-antistop particles produced in $e^{+}{e}^{-}$ annihilation: $e^{+}{e}^{-}\to \tilde{t}\overline{\stackrel{~}{t}}g$. For high energies the splitting functions of the fragmentation processes $\tilde t \to \tilde t g$and$g \to \tilde t \bar{\tilde t}$ are derived; they are universal and apply also to high-energy stop particles produced at hadron colliders.
