Search for W’ decays taking into account interference effects with pp-collisions at √s = 13 TeV in the ATLAS experiment — •Paul Gessinger and Stefan Tapprogge — Johannes Gutenberg-Universität Mainz

As part of the search for new physics, the electronic decay of new heavy charged gauge bosons, W′ → eν, can be looked for in pp-collisions at √s = 13 TeV in the ATLAS experiment at the LHC. Events with a lepton of high transverse momentum and high missing transverse energy are selected. If no significant excess is observed, statistical methods can be employed to calculate a lower limit on the mass of a hypothetical W′ particle. Narrow resonance signal templates are used, either taking into account interference with the background processes, or neglecting it. Interference effects modify the overall signal shape and can thus impact the limit obtained. The results of both approaches will be presented and discussed.
