Inclusive search for squark and Gluino production in pp̄ collisions at s=1.96TeV

We report on a search for inclusive production of squarks and gluinos in pp collisions at {radical}(s)=1.96 TeV, in events with large missing transverse energy and multiple jets of hadrons in the final state. The study uses a CDF Run II data sample corresponding to 2 fb{sup -1} of integrated luminosity. The data are in good agreement with the standard model predictions, giving no evidence for any squark or gluino component. In an R-parity conserving minimal supergravity scenario with A{sub 0}=0, {mu}<0, and tan{beta}=5, 95% C.L. upper limits on the production cross sections in the range between 0.1 and 1 pb are obtained, depending on the squark and gluino masses considered. For gluino masses below 280 GeV/c{sup 2}, arbitrarily large squark masses are excluded at the 95% C.L., while for mass degenerate gluinos and squarks, masses below 392 GeV/c{sup 2} are excluded at the 95% C.L.
