Abstract Data collected in Run II of the Fermilab Tevatron are searched for indications of new electroweak-scale physics. Rather than focusing on particular new physics scenarios, CDF data are analyzed for discrepancies with the Standard Model prediction. A model-independent approach (Vista) considers gross features of the data, and is sensitive to new large cross-section physics. Further sensitivity to new physics is provided by two additional algorithms: a ``Bump-Hunter'' searches invariant mass distributions for ``bumps'' that could indicate resonant production of new particles; and the Sleuth procedure scans for data excesses in the high-pT tails. This combined global search for new physics in 2.0/fb of p-pbar collisions at sqrt(s)=1.96 TeV reveals no indication of physics beyond the Standard Model.
