Using 425  pb(−1) of data collected using the D0 detector at the Fermilab Tevatron Collider, and enhancing the tt-bar content of the sample by tagging b jets with a secondary vertex tagging algorithm, the tt-bar production cross section is measured to be σpp-bar→tt-bar+X=6.6±0.9(stat+syst)±0.4(lum)  pb. This cross section is the most precise D0 measurement to date for tt-bar production and is in good agreement with standard model expectations.Article10.1103/PhysRevD.74.112004openAccess
