Book excerpt: We present a measurement of the t{bar t} production cross section multiplied by the branching ratio to tau lepton decaying semi-hadronically ([tau]{sub h}) plus jets, [sigma](p{bar p} → t{bar t} + X) · BR(t{bar t} → [tau]{sub h} + jets), at a center of mass energy √s = 1.96 TeV using 1 fb−1 of integrated luminosity collected with the D0 detector. Assuming a top quark mass of 170 GeV, we measure [sigma]{sub t{bar t}} · BR{sub [tau]{sub h}+j} = 0.60{sub -0.22}{sup +0.23}(stat){sub -0.14}{sup +0.15}(syst)±0.04 (lumi) pb. In addition, we extract the t{bar t} production cross section using the t{bar t} → {tau}{sub h} + jets topology, with the result [sigma]{sub t{bar t}} = 6.9{sub -1.2}{sup +1.2}(stat){sub -0.7}{sup +0.8}(syst) ± 0.4 (lumi) pb. These findings are in good agreement with standard model predictions and measurements performed using other top quark decay channels.
