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...

| description | 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
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. |
