We search for direct pair production of supersymmetric top
quarks and supersymmetric bottom quarks in proton-antiproton collisions
at s**(1/2) = 1.96 TeV, using 295 pb-1 of data recorded by the Collider
Detector at Fermilab (CDF II) experiment. The supersymmetric top
(supersymmetric bottom) quarks are selected by reconstructing their decay
into a charm (bottom) quark and a neutralino, which is assumed to be the
lightest supersymmetric particle. The signature of such processes is two
energetic heavy-flavor jets and missing transverse energy. The number
of events that pass our selection for each search process is consistent
with the standard model expectation. By comparing our results to the
theoretical production cross sections of the supersymmetric top quark mass
up to 132 GeV/c2 for a neutralino mass of 48 GeV/c2, and a supersymmetric
bottom quark mass up to 193 GeV/c2 for a neutralino mass of 40 GeV/c2.
