Prospects of detecting massive isosinglet neutrino at LHC in the CMS detector

A possibility to search for a heavy isosinglet (sterile) neutrino using its decay mode $\nu_s \to l^{\pm} + 2 jets$ in the S - channel production $pp \to W^* + X \to l^{\pm}\nu_s + X$ in the CMS experiment is studied. The only assumption about the heavy neutrino is its nonzero mixing with $\nu_e$ or...

description A possibility to search for a heavy isosinglet (sterile) neutrino using its decay mode $\nu_s \to l^{\pm} + 2 jets$ in the S - channel production $pp \to W^* + X \to l^{\pm}\nu_s + X$ in the CMS experiment is studied. The only assumption about the heavy neutrino is its nonzero mixing with $\nu_e$ or $\nu_{\mu}$. 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 GeVcould be detected in CMS. We also investigate the production of the heavy neutrino in the $SU_C(3) \otimes SU_L(2) \otimes SU_R(2)\otimes U(1)$ model through the reaction $pp \to W_R + X \to l^{\pm}\nu_s + X$ with the same heavy neutrino decay channel as above. We find that for $M_{W_R} < 3 TeV$ it is possible to discover the heavy neutrino with a mass up to $0.75 \cdot M_{W_R}$.
