Query: New Signatures for a Light Stop at LEP2 in SUSY Models with
  Spontaneously Broken R-Parity   In a class of supersymmetric models with R-parity breaking the lightest stop
can have new decay modes into third generation fermions, $\tilde{t}_1
\rightarrow b + \tau$. We show that this decay may be dominant or at least
comparable to the ordinary R-parity conserving mode $\tilde{t}_1 \rightarrow c
+ \tilde{\chi}_1^0$, where $\tilde{\chi}_1^0$ denotes the lightest neutralino.
The new R-parity violating decay mode could provide new signatures for stop
production at LEP.
