Measurement of the t-channel Single Top-Quark Production Cross Section in 0.70fb^-1 of pp Collisions at sqrt(s) = 7 TeV with the ATLAS detector

We report a measurement of the cross section of single top-quark production in the t-channel mode using 0.70 fb^-1 of pp collision data sqrt(s)=7 TeV recorded with the ATLAS detector at the LHC. Selected events contain one electron or muon, missing transverse energy, and two or three jets, exactly o...

description We report a measurement of the cross section of single top-quark production in the t-channel mode using 0.70 fb^-1 of pp collision data sqrt(s)=7 TeV recorded with the ATLAS detector at the LHC. Selected events contain one electron or muon, missing transverse energy, and two or three jets, exactly one of them being identified as coming from a b~quark. The t-channel production cross section is measured by two different techniques, one following a cut-based approach and one fitting the distribution of a multivariate discriminant constructed with a neural network. The cut-based analysis combines the 2-jet and 3-jet data sets and measures sigma_t = 90 +32 -22 pb.
