Searches for the Supersymmetric Partner of the Bottom Quark
  We have performed a search for the scalar bottom quark from gluino decays in an R-parity conserving SUSY scenario with m(gluino) > m(sbottom), by investigating a final state of large missing transverse energy, with three or more jets, and some of them from the hadronization of b-quarks. A data sample of 156pb-1 collected by the Collider Detector at Fermilab at a center-of-mass energy of 1.96TeV was used. For the final selection, jets containing secondary displaced vertices were required. This analysis has been performed 'blind', in that the inspection of the signal region was only made after the standard model prediction was fina lized. Comparing data with SUSY predictions, we can exclude masses of the gluino and sbottom of up to 280 and 240GeV/c^2 respectively.
