A measurement of the t anti-t production cross-section in proton anti-proton collisions at √s = 1.96-TeV with the D0 detector at the Tevatron using final states with a muon and jets
- Univ. of Bonn (Germany)
A preliminary measurement of the t$$\bar{t}$$ production cross section at √s = 1.96 TeV is presented. The μ-plus-jets final state is analyzed in a data sample of 94 pb-1 and a total of 14 events are selected with a background expectation of 11.7 ± 1.9 events. The measurement yields: σp$$\bar{p}$$ → t$$\bar{t}$$ + X} = 2.4$$+4.2\atop{-3.5}$$(stat.)$$+2.5\atop{-2.6}$$(syst.) ± 0.3(lumi.) pb. The analysis, being part of a larger effort to re-observe the top quark in Tevatron Run II data and to measure the production cross section, is combined with results from all available analyses channels. The combined result yields: σ p$$\bar{p}$$ → t$$\bar{t}$$ + X = 8.1$$+2.2\atop{-2.0}$$(stat.)$$+1.6\atop{-1.4}$$(syst.) ± 0.8(lumi.) pb.
