Search for a heavy neutrino and right-handed W of the left-right symmetric model in pp collisions

We describe the search for signals from the production of right-handed W bosonsand heavy neutrinos $N_l (l = e, \mu)$, that arise naturally in the left-right symmetricextension to the standard model, using 5 1/fb of collision data collected by the CMSExperiment at the LHC in 2011 at $\sqrt{s}=7$ TeV...

Sumario:We describe the search for signals from the production of right-handed W bosonsand heavy neutrinos $N_l (l = e, \mu)$, that arise naturally in the left-right symmetricextension to the standard model, using 5 1/fb of collision data collected by the CMSExperiment at the LHC in 2011 at $\sqrt{s}=7$ TeV and 3.6 1/fb of 2012 collisiondata at $\sqrt{s}=8$ TeV. No excess over expectations from standardmodel processes is observed. For models with exact left-right symmetry, and assumingeither $N_e$ or $N_{\mu}$ is the only right-handed neutrino accessible at LHC energies, weexclude the region in the two-dimensional parameter $(M_{W_R}, M_N)$ space that extendsbeyond $M_{W_R}$ = 2.5 TeV.
