Light $\text{stop}\to \text{wino}b$ models are not ruled out by the Tevatron top experiments

Abstract

SUSY events in which a light stop decays to a chargino may manage to pass the cuts designed for top counting experiments at the Tevatron with no significant diminution of signal. Events in which a top decays via stop are detected with fair efficiency compared to SM top events when $\text{stop}\text{into}b\text{wino}$. More importantly, direct pair production of light stops contributes significantly to the cut samples. Many SUSY models with stops lighter than 100 GeV are viable even for $\Gamma (t\text{into}\text{stop})\approx \Gamma (t\text{into}bW)$.
