In this Letter, we present a precise measurement of the total production cross section in collisions at , using data collected with the CDF II detector corresponding to an integrated luminosity of approximately . The result is obtained by combining separate measurements in the four-charged () and two-charged-lepton and two-neutral-lepton () decay modes of the boson pair. The combined measured cross section for is . This is the most precise measurement of the production cross section in 1.96 TeV collisions to date.
