Search for a new heavy gauge-boson resonance decaying into a lepton and missing transverse momentum in 36 fb of collisions at TeV with the ATLAS experiment.

The results of a search for new heavy bosons decaying to an electron or muon and a neutrino using proton-proton collision data at a centre-of-mass energy of  TeV are presented. 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  . As no excess of events above the Standard Model prediction is observed, the results are used to set upper limits on the boson cross-section times branching ratio to an electron or muon and a neutrino as a function of the mass. Assuming a boson with the same couplings as the Standard Model boson, masses below 5.1 TeV are excluded at the 95% confidence level.
