Search for new resonances in events with one lepton and missing transverse momentum in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector

Understand

A search for $W^\prime$ bosons in events with one lepton (electron or muon) and missing transverse momentum is presented.

• The search uses 3.2 fb$^{-1}$ of $pp$ collision data collected at $\sqrt{s} = 13$ TeV by the ATLAS experiment at the LHC in 2015.
• The transverse mass distribution is examined and no significant excess of events above the level expected from Standard Model processes is observed.
• Upper limits on the $W^\prime$ boson cross-section times branching ratio to leptons are set as a function of the $W^\prime$ mass.
