Abstract

We present results of the search for the super-symmetric partner of the top\nquark, the stop quark, decaying to a b-quark and chargino with the subsequent\nchargino decay into a neutralino, lepton and neutrino. Using the data sample\ncorresponding to 2.7 inv fb of integrated luminosity, collected with the CDF\nDetector of the Tevatron collider, we reconstruct the stop mass of candidate\nevents and set 95% C. L. upper limits on masses of the stop quark, chargino and\nneutralino and the branching ratio of chargino to neutralino+lepton+neutrino.\n
