  Events with signatures involving large missing transverse energy (MET) are
among the quintessential search modes for R-parity conserving supersymmetry.
CDF has conducted two recent analyses for supersymmetry which use MET and jets.
The MET and monojet signature is employed to determine process independent
limits for the production of new physics beyond the Standard Model and then
applied to models of spontaneous breaking of supersymmetry to determine limits
on the supersymmetry breaking parameter and the gravitino mass. Direct searches
for scalar top and scalar bottom quarks within the framework of supersymmetric
models are performed using a signature of MET and two heavy flavor jets. Since
the data is found to be consistent with Standard Model expectations, limits are
determined in the mass planes $m (\tilde{\chi}_{1}^{0}) - m (\tilde{t}_{1})$
and $m (\tilde{\chi}_{1}^{0}) - m (\tilde{b}_{1})$.
