| 英文摘要 | 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 root s = 13 tevis 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-l, stems from a composite-fermion scenario. exclusion limits are set for the first time on the mass of the heavy composite majorana neutrino, m(nl), and the compositeness scale lambda. for the case m(nl) = lambda, the existence of n-e (n-mu) is excluded for masses up to 4.60 (4.70) tev at 95% confidence level.
