Using a data sample corresponding to 2.7  fb-1 of integrated luminosity of pp̅ collisions at √s=1.96  TeV collected by the CDF II detector, we reconstruct the mass of top squark candidate events and fit the observed mass spectrum to a combination of standard model processes and t1t̅ 1 signal. We find no evidence for t1t̅ 1 production and set 95% C.L. limits on the masses of the top squark and the neutralino for several values of the chargino mass and the branching ratio B(χ1±→χ10ℓ±ν).
