Abstrakt: In a class of supersymmetric models with R-parity breaking the lightest stop can have new decay modes into third generation fermions, t1→ b + τ. We show that this decay may be dominant or at least comparable to the ordinary R-parity conserving mode t1→ c + χ10, where χ10denotes the lightest neutralino. The new R-parity violating decay modes could provide new signatures for stop production at LEP.
