Abstract
 We present a new method for studying high-pT dilepton events (e±e∓, μ±μ∓, e±μ∓) and simultaneously extracting the production cross sections of pp̅ →tt̅ , pp̅ →W+W-, and pp̅ →Z0→τ+τ- at a center-of-mass energy of √s=1.96  TeV. We perform a likelihood fit to the dilepton data in a parameter space defined by the missing transverse energy and the number of jets in the event. Our results, which use 360  pb-1 of data recorded with the CDF II detector at the Fermilab Tevatron Collider, are σ(tt̅ )=8.5-2.2+2.7   pb, σ(W+W-)=16.3-4.4+5.2   pb, and σ(Z0→τ+τ-)=291-46+50   pb.
