noimgThe observed numbers of events in the data in the \ejets\ and \mjets\ channels, for the two analyses after the common event selection and additional analysis-specific requirements. In addition, the expected numbers of signal and background events corresponding to the integrated luminosity of the data are given, where the single top quark production events are treated as signal for the \od, and as background for the \td. The Monte Carlo estimates assume SM cross-sections. The \Wj\ and QCD multijet background contributions are estimated from ATLAS data. The uncertainties for the estimates include different components detailed in the text. All predicted event numbers are quoted using one significant digit for the uncertainties, i.e.~the trailing zeros are insignificant.

Distributions for the selected events of the common event selection in the \ejets\ channel on the left and the \mjets\ channel on the right. Shown are (a, b) the measured jet multiplicities, (c, d) the \pt, and (e, f) the $\eta$ distributions of all selected jets. The hatched area is the total uncertainty on the prediction described in the text. In (c, d) the rightmost bin also contains the overflow.Caption not extracted

\ejets\ channel

\ejets\ channel{\bf \od:} Performance of the likelihood fit in the \ejets\ channel. Shown in (a) are the predicted \lnL\ distributions for various jet permutations in the \ttbar\ signal Monte Carlo. The figures (b, c) compare two output variables of the likelihood fit as observed in the data with their respective prediction. These are (b) the \lnL\ value, and (c) the \pt\ of the \bjet\ associated to the hadronic decay of the top quark.
