Search for a new heavy gauge-boson resonance decaying into a lepton and missing transverse momentum in 36 fb(-1) of pp collisions root s=13 TeV with the ATLAS experiment

Abstract

The results of a search for new heavy

W '

bosons decaying to an electron or muon and a neutrino using proton-proton collision data at a centre-of-mass energy of

s

=

13

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

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 '

boson cross-section times branching ratio to an electron or muon and a neutrino as a function of the

W '

mass. Assuming a

W '

boson with the same couplings as the Standard Model W boson,

W '

masses below 5.1 TeV are excluded at the 95% confidence level.
