We have searched for direct pair production of scalar top and
scalar bottom quarks in 88 pb-1 of p anti-p collisions at s**(1/2) = 1.8 TeV
with the CDF detector. We looked for events with a pair of heavy flavor
jets and missing energy, consistent with scalar top quark decays to a charm
quark and a neutralino, or scalar bottom quark decays to a bottom quark and
a neutralino. The numbers of events that pass our selection for each
process show no deviation from Standard Model expectations. We compare our
results to next-to-leading order calculations for the scalar quark
production cross sections to exclude regions in scalar quark-neutralino
parameter space.
