Observation of t Channel Single Top-Quark Production in pp Collisions at $sqrt{s} = 7$~TeV with the ATLAS detector

We report the observation of single top-quark production in the t-channel mode using 156 pb-1 of $pp$ collision data at sqrt(s)=7 TeV recorded with the ATLAS detector at CERN. Selected events contain one lepton, missing transverse energy, and exactly two jets, exactly one of them being identified as...

description We report the observation of single top-quark production in the t-channel mode using 156 pb-1 of $pp$ collision data at sqrt(s)=7 TeV recorded with the ATLAS detector at CERN. Selected events contain one lepton, missing transverse energy, and exactly two jets, exactly one of them being identified as coming from a b-quark. We show comparisons of data to a compound background model for kinematic distributions and measure the t-channel production cross section using a cut-based approach and using a multivariate discriminant constructed with a neural network.
