Received 28 December 2006; published 14 July 2008
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.
