We present a new method for studying high-p(t) dilepton events
(e+/- e-/+, mu+/- mu-/+, e+/- mu-/+) and simultaneously extracting the
production cross sections of p anti-p --> tt-bar, p anti-p --> W+
w-, and p anti-p -> Z0 --> tau+ tau- at a center-of-mass energy
of s**(1/2) ñ.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 sigma(tt-bar) ø.5+2.7_-2.2 pb, sigma(W+ W-) ñ6.3+5.2_-4.4 pb, and
sigma(Z0 --> tau+ tau-) 291+50_-46 pb.
