A possibility to search for a heavy isosinglet (sterile) neutrino using its decay mode νs → l± + 2 jets in the S - channel production pp → W^* + X → l±νs + X in the CMS experiment is studied. The only assumption about the heavy neutrino is its nonzero mixing with νe or νμ. The corresponding CMS discovery potential expressed in terms of the heavy neutrino mass and the mixing parameter between the heavy and light neutrino is determined. It is shown that the heavy neutrino with a mass up to 800 GeV could be detected in CMS. We also investigate the production of the heavy neutrino Nl mixed with νe and/or νμ in the SUC(3) ⊗ SUL(2) ⊗ SUR(2)⊗ U(1) model through the reaction pp → WR + X → l±Nl + X with the same heavy neutrino decay channel as above. We find that for MWR < 3 TeV it is possible to discover the heavy neutrino with a mass up to 0.75 ⋅ MWR.
