The dataset was collected in 2015 and 2016 by the ATLAS experiment at the Large Hadron Collider and corresponds to an integrated luminosity of 36.1  $\text{ fb }^{-1}$ . As no excess of events above the Standard Model prediction is observed, the results are used to set upper limits on the $W^\prime $ boson cross-section times branching ratio to an electron or muon and a neutrino as a function of the $W^\prime $ mass. Assuming a $W^\prime $ boson with the same couplings as the Standard Model W boson, $W^\prime $ masses below 5.1 TeV are excluded at the 95% confidence level.engjournal article2019-02-04
