Summary:
Using data collected during the 1992--1993 collider run at Fermilab, CDF has reconstructed several hundred charmed mesons (D°, D⁺, D{sup *+} and D{sub s}) in association with leptons from B semileptonic decays. We report on a measurement of the cross section of B and B{sub s} mesons as a function of transverse momentum this sample. The observation of a charmed meson eliminates many systematic uncertainties in the background subtraction inherent in previous measurements from inclusive lepton samples, and allows the backgrounds to be measured from the data. The B meson PT range probed by the lepton+charm technique is 18 GeV and above, and thus these measurements complement similar measurements at lower PT in the fully exclusive channels B → J/ψK and B → J/ψK{sup *}. Results are compared to other Tevatron measurements and Next-To-Leading-Order QCD predictions.
