Query: Gluon Radiation Off Scalar Stop Particles   We present the distributions for gluon radiation off stop-antistop particles
produced in $e^+e^-$ annihilation: $e^+e^- \to \tilde t \bar{\tilde t} g$. 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.
