Description
We describe the search for signals from the production of right-handed W bosons and heavy neutrinos $N_l (l = e, \mu)$, that arise naturally in the left-right symmetric extension to the standard model, using 5 1/fb of collision data collected by the CMS Experiment at the LHC in 2011 at $\sqrt{s}=7$ TeV and 3.6 1/fb of 2012 collision data at $\sqrt{s}=8$ TeV. No excess over expectations from standard model processes is observed. For models with exact left-right symmetry, and assuming either $N_e$ or $N_{\mu}$ is the only right-handed neutrino accessible at LHC energies, we exclude the region in the two-dimensional parameter $(M_{W_R}, M_N)$ space that extends beyond $M_{W_R}$ = 2.5 TeV.
