Search for a heavy composite Majorana neutrino in the final state with two leptons and two quarks at s=13TeV

A search for physics beyond the standard model in the final state with two same-flavour leptons (electrons or muons) and two quarks produced in proton–proton collisions at √s = 13 TeV is presented. The data were recorded by the CMS experiment at the CERN LHC and correspond to an integrated lumino...
