摘要：

SUSY events in which a light top squark decays to a chargino may manage to pass the cuts designed for top counting experiments at the Fermilab Tevatron with no significant diminution of signal. Events in which a top decays via a top squark are detected with fair efficiency compared to SM top events when (t) over tilde(l)-->b (W) over tilde(l). More importantly, direct pair production of light top squarks contributes significantly to the cut samples. Many SUSY models with top squarks lighter than 100 GeV are viable even for Gamma(t-(t) over tilde(l))approximate to Gamma(t-->bW).
