Search for a heavy right-handed W boson and a heavy neutrino in events with two same-flavor leptons and two jets at √s=13 TeV

A search for a heavy right-handed W boson (WR) decaying to a heavy righthanded neutrino and a charged lepton in events with two same-flavor leptons (e or µ) and two jets, is presented. The analysis is based on proton-proton collision data, collected by the CMS Collaboration at the LHC in 2016 and...
