  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.
