Combined Single-Top Search with Early ATLAS Data

We use simulated events to examine the potential to observe the production of a single-top quark in the early ATLAS data. For integrated luminosities of less than $\rm 100~pb^{-1}$, multivariate techniques are used to extract the single-top quark signal, which is small compared to the background. Two separate samples are considered, one containing 1 $b$-tagged jet and another containing 2 $b$-tagged jets. In both samples, the three single-top channels are combined to allow for consideration of the full single-top quark signal.
