Single-top analysis optimization for the ATLAS 10 TeV run at the LHC — Markus Cristinziani, •Gia Khoriauli, Marc Lehmacher, Agnieszka Leyko, Gizo Nanava, Tatevik Poghosyan, Nina Scislak, Duc Bao Ta, and Nikolai Vlasov — Physikalisches Institut, Universität Bonn
The production of single top at the LHC is expected to be substantial, approximately one third of the top-pair production cross section. However, the final states are difficult to distinguish from Standard Model background and therefore a careful optimization of the object selection and topological cuts is needed. Once a statistically significant data sample has been collected, this optimization will be calibrated with data. We present methods and results of this optimization for an integrated luminosity of 100 pb−1 for ATLAS.
