Özet
A search for physics beyond the standard model in the final state with two sameflavour 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 luminosity of 2.3 fb?1 . The observed data are in good agreement with the standard model background prediction. The results of the measurement are interpreted in the framework of a recently proposed model in which a heavy Majorana neutrino, N` , stems from a composite-fermion scenario. Exclusion limits are set for the first time on the mass of the heavy composite Majorana neutrino, mN` , and the compositeness scale ?. For the case mN` = ?, the existence of Ne (Nµ) is excluded for masses up to 4.60 (4.70) TeV at 95% confidence level
