Decays of top-quark pairs into the final states ev + jets and μv+ jets are selected, and the cross section and the b-jet identification efficiency are determined using a new measurement technique which requires agreement between the measured cross sections with exactly one and with multiple identified b quarks from the top-quark decays. Assuming a top-quark mass of 175 GeV/c(2), a cross section of 8.5 +/- 0.6(stat) +/- 0.7(syst)pb is measured. %R 10.1103/PhysRevD.83.071102 %U http://arxiv.org/abs/arXiv:1007.4423 %U https://doi.org/10.1103/PhysRevD.83.071102 %P 071102-8pp
