Measurement of the tt̄ production cross section in pp̄ collisions at s=1.96TeV using secondary vertex b tagging
We report a new measurement of the tt̄ production cross section in pp̄ collisions at a center-of-mass energy of 1.96 TeV using events with one charged lepton (electron or muon), missing transverse energy, and jets. Using 425pb-1 of data collected using the D0 detector at the Fermilab Tevatron Collid...

| description | We report a new measurement of the tt̄ production cross section in pp̄ collisions at a center-of-mass energy of 1.96 TeV using events with one charged lepton (electron or muon), missing transverse energy, and jets. Using 425pb-1 of data collected using the D0 detector at the Fermilab Tevatron Collider, and enhancing the tt̄ content of the sample by tagging b jets with a secondary vertex tagging algorithm, the tt̄ production cross section is measured to be σpp̄→tt̄+X=6.6±0.9(stat+syst) ±0.4(lum)pb. This cross section is the most precise D0 measurement to date for tt̄ production and is in good agreement with standard model expectations. © 2006 The American Physical Society. |
