We report on a search for direct scalar bottom quark (sbottom)
pair production in p anti-p collisions at s**(1/2) ñ.96 TeV, in events
with large missing transverse energy and two jets of hadrons in the final
state, where at least one of the jets is required to be identified as
originating from a b quark. The study uses a CDF Run II data sample
corresponding to 2.65 fb-1 of integrated luminosity. The data are in
agreement with the standard model. In an R-parity conserving minimal
supersymmetric scenario, and assuming that the sbottom decays exclusively
into a bottom quark and a neutralino, 95% confidence-level upper limits
on the sbottom pair production cross section of 0.1 pb are obtained.
For neutralino masses below 70 GeV/c2, sbottom masses up to 230 GeV/c2
are excluded at 95% confidence level.
