Evidence for the associated production of a W boson and a top quark in ATLAS at √s = 7 TeV

Abstract:

This Letter presents evidence for the associated production of a W boson and a top quark using 2.05 fb-1 of pp collision data at s=7TeV accumulated with the ATLAS detector at the LHC. The analysis is based on the selection of the dileptonic final states with events featuring two isolated leptons, electron or muon, with significant transverse missing momentum and at least one jet. An approach based on boosted decision trees has been developed to improve the discrimination of single top-quark W...
