Search for a heavy neutrino and right-handed W of the left-right symmetric model in pp collisions at sqrt(s) =7 TeV

We search for signals from the production of right-handed $W_R$ bosons and heavy electron neutrinos $N_e$, that arise naturally in the left-right symmetric extensions to the Standard Model. The search is performed with the CMS Experiment at the LHC using the 7 TeV $pp$ collision data collected in 2011 and corresponding to an integrated luminosity of 5~fb$^{-1}$. No excess over expectations from Standard Model processes is observed. For models with the same coupling in the left and right sectors, we exclude the region in the two-dimensional parameter space that extends up to ($M_{W_R}$, $M_{N_e}$) = (2500~GeV, 800~GeV).
