Data-driven background estimation in Charged Higgs searches in ATLAS

In this talk I will present an application of the fake factor method for background modelling in H+ -> tau nu search using 36.1 fb^-1 of pp collision data at s =sqrt(13) TeV recorded by the ATLAS detector. In this technique background processes where a jet is reconstructed and selected as a tau c...

description In this talk I will present an application of the fake factor method for background modelling in H+ -> tau nu search using 36.1 fb^-1 of pp collision data at s =sqrt(13) TeV recorded by the ATLAS detector. In this technique background processes where a jet is reconstructed and selected as a tau candidate are estimated from data using correction (fake) factors obtained in dedicated control regions. Separate fake factors derived for quark- and gluon-initiated jets are combined using template fit method based on discriminating variables sensitive to the origin of the jet.
