Study of ATLAS sensitivity to asymmetries in single top events

The study of the LHC ATLAS experiment sensitivity to angular and spin asymmetries in the production of single top quarks (t-channel) events was done using the fast detector simulation (ATLFAST) and all the events were generated using PYTHIA and TopReX libraries. In order to get an efficient selection of events, a likelihood-based analysis was developed for a luminosity of 10 fb^-1. From the measurement of these asymmetries, the limits at 68.3% confidence level on the anomalous couplings of the Wtb vertex were set using the TopFit library.
