Measurement of the B cross section at CDF via B semileptonic decays
Using data collected during the 1992--1993 collider run at Fermilab, CDF has reconstructed several hundred charmed mesons (D{sup 0}, D{sup +} 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 using 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 p{sub T} range probed by the lepton + charm technique is 18 GeV and above, and thus these measurements complement similar measurements at lower p{sub T} in the fully exclusive channels B {yields} J/{psi}K and B {yields} J/{psi}K*. Results are compared to other Tevatron measurements and Next-To-Leading-Order QCD predictions.
