Description
The second largest background of this $W^{\pm}jj-EW$ signal originates from misidentified leptons, also known as non-prompt leptons. One approach employed to properly estimate this background is the data-driven fake factor method, which requires fake factors extracted from a defined control region. In this work, two trilepton validation regions were defined in order to test the fake factors calculated from a dilepton control region, which is intented to be a cross-check for the nominal fake studies. The data studied were measured with the ATLAS experiment at a collision energy of 13 TeV with an integrated luminosity of 138.7 fb$^{-1}$.
