Combination of single top-quark cross-section measurements in the t channel at sqrt[s] = 8 TeV with the ATLAS and CMS experiments

A combination of measurements of the single top-quark production cross-section in the $t$ channel at $\sqrt{s}=8$~TeV by the ATLAS and CMS experiments at the LHC is presented. The measurements from ATLAS and CMS are based on integrated luminosities of 5.8~fb$^{-1}$ and 5.0~fb$^{-1}$, respectively....

description A combination of measurements of the single top-quark production cross-section in the $t$ channel at $\sqrt{s}=8$~TeV by the ATLAS and CMS experiments at the LHC is presented. The measurements from ATLAS and CMS are based on integrated luminosities of 5.8~fb$^{-1}$ and 5.0~fb$^{-1}$, respectively. The best linear unbiased estimator (BLUE) method is applied for the combination, taking into account the individual contributions to systematic uncertainties of the two experiments and their correlations. The combined single top-quark production cross-section in the $t$ channel is $ \sigma_{t\text{-ch.}} = 85 \pm 4 \, \mathrm{(stat.)} \pm 11 \, \mathrm{(syst.)}\pm 3 \, \mathrm{(lumi.)}\,\mathrm{pb} = 85 \pm 12 \,\mathrm{pb}$, in agreement with the theoretical predictions.
