Abstract (data abstract)

CERN-LHC. A search for heavy right-handed Majorana or Dirac neutrinos and heavy right-handed $W$ gauge bosons is performed in events with a pair of energetic electrons or muons, with the same or opposite electric charge, and two energetic jets. The events are selected from $pp$ collision data with an integrated luminosity of 36 fb$^{-1}$ collected by the ATLAS detector at a centre-of-mass energy of 13 TeV. No significant deviations from the Standard Model are observed. The results are interpreted within the theoretical framework of a left-right symmetric model and lower mass limits are set in the heavy right-handed W and neutrino mass plane. The excluded region extends to $m_{W_R}~= 4.7$ TeV for both Majorana and Dirac $N_R$ neutrinos.
