Combination of measurements of the top-quark pair production cross section from the Tevatron Collider

We combine six measurements of the inclusive top-quark pair (tt) production cross section ([sigma]tt) from data collected with the CDF and DO detectors at the Fermilab Tevatron with proton-antiproton collisions at [radical]s = 1.96 TeV. The data correspond to integrated luminosities of up to 8.8 fb...

Zusammenfassung:	We combine six measurements of the inclusive top-quark pair (tt) production cross section ([sigma]tt) from data collected with the CDF and DO detectors at the Fermilab Tevatron with proton-antiproton collisions at [radical]s = 1.96 TeV. The data correspond to integrated luminosities of up to 8.8 fb super(-1). We obtain a value of [sigma]tt = 7.60 + or - 0.41 pb for a top-quark mass of mt = 172.5 GeV. The contributions to the uncertainty are 0.20 pb from statistical sources, 0.29 pb from systematic sources, and 0.21 pb from the uncertainty on the integrated luminosity. The result is in good agreement with the standard model expectation of (ProQuest: Formulae and/or non-USASCII text omitted) pb at next-to-next-to-leading order and next-to-next-to leading logarithms in perturbative QCD.
