Type: article
Abstract: We present a measurement of the inclusive top quark pair production cross section in $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ utilizing data corresponding to an integrated luminosity of $5.3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected with the D0 detector at the Fermilab Tevatron Collider. We consider final states containing one high-${p}_{T}$ isolated electron or muon and at least two jets, and we perform three analyses: one exploiting specific kinematic features of $t\overline{t}$ events, the second using $b$-jet identification, and the third using both techniques to separate the $t\overline{t}$ signal from the background. In the third case, we determine simultaneously the $t\overline{t}$ cross section and the ratio of the production rates of $W+\mathrm{\text{heavy}}$ flavor jets and $W+\mathrm{\text{light}}$ flavor jets, which reduces the impact of the systematic uncertainties related to the background estimation. Assuming a top quark mass of 172.5 GeV, we obtain ${\ensuremath{\sigma}}_{t\overline{t}}={7.78}_{\ensuremath{-}0.64}^{+0.77}\text{ }\text{ }\mathrm{pb}$. This result agrees with predictions of the standard model.
