Search for heavy Majorana or Dirac neutrinos and right-handed W gauge bosons in final states with charged leptons and jets in pp collisions at SQUARE ROOTs = 13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search for heavy right-handed Majorana orDirac neutrinos NR and heavy right-handed gauge bosonsWR is performed in eventswith energetic electrons or muons,with the same or opposite electric charge, and energeticjets. The search is carried out separately for topologies ofclearly separated final-state products (&quot;resolved&quot; channel)and topologies with boosted final states with hadronic and/orleptonic products partially overlapping and reconstructedas a large-radius jet (&quot;boosted&quot; channel). The events areselected from pp collision data at the LHCwith an integratedluminosity of 139 fb-1 SQUARE ROOT collected by the ATLAS detector ats = 13 TeV. No significant deviations from the StandardModel predictions are observed. The results are interpretedwithin the theoretical framework of a left-right symmetricmodel, and lower limits are set on masses in the heavy righthandedWRboson and NR plane. The excluded region extendsto about m(WR) = 6.4 TeV for bothMajorana and Dirac NRneutrinos at m(NR) &lt; 1 TeV. NR with masses of less than3.5 (3.6) TeV are excluded in the electron (muon) channelat m(WR) = 4.8 TeV for the Majorana neutrinos, and limitsof m(NR) up to 3.6 TeV for m(WR) = 5.2 (5.0) TeV inthe electron (muon) channel are set for the Dirac neutrinos.These constitute the most stringent exclusion limits to datefor the model considered.
