Search for heavy Majorana neutrinos in ????±????± and ????±????± final states via WW scattering in ???????? collisions at √???? = 13 TeV with the ATLAS detector
Original language description
A search for heavy Majorana neutrinos in scattering of same-sign ???? boson pairs in proton-proton collisions at SQUARE ROOT???? = 13 TeV at the LHC is reported. The dataset used corresponds to an integrated luminosity of 140 fb-1, collected with the ATLAS detector during 2015-2018. The search is performed in final states including a same-sign ???????? or ???????? pair and at least two jets with large invariant mass and a large rapidity difference. No significant excess of events with respect to the Standard Model background predictions is observed. The results are interpreted in a benchmark scenario of the Phenomenological Type-I Seesaw model. New constraints are set on the values of the |????????????|2 and |???????????????? ASTERISK OPERATOR????????| parameters for heavy Majorana neutrino masses between 50 GeV and 20 TeV, where ????????????is the matrix element describing the mixing of the heavy Majorana neutrino mass eigenstate with the Standard Model neutrino of flavour ???? = ????, ????. The sensitivity to the Weinberg operator is investigated and constraints on the effective ???????? and ???????? Majorana neutrino masses are reported.
