Search for Majorana neutrinos in same-sign WW scattering events from pp collisions at √s=13 TeV
Original language description
A search for Majorana neutrinos in same-sign WW scattering events is presented. The analysis uses s=13s =13 TeV proton–proton collision data with an integrated luminosity of 140 fb−1−1 recorded during 2015–2018 by the ATLAS detector at the Large Hadron Collider. The analysis targets final states including exactly two same-sign muons and at least two hadronic jets well separated in rapidity. The modelling of the main backgrounds, from Standard Model same-sign WW scattering and WZ production, is constrained with data in dedicated signal-depleted control regions. The distribution of the transverse momentum of the second-hardest muon is used to search for signals originating from a heavy Majorana neutrino with a mass between 50 GeV and 20 TeV. No significant excess is observed over the background expectation. The results are interpreted in a benchmark scenario of the Phenomenological Type-I Seesaw model.
