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

This Note describes the first search for signals from the production of right-handed $W_R$ bosons and heavy neutrinos $N_{\ell}$ ($\ell = e,\mu$), that arise naturally in the left-right symmetric extension to the Standard Model, with the CMS Experiment at the LHC using the 7 TeV $pp$ collision data collected in 2010 and 2011 corresponding to an integrated luminosity of 240~pb$^{-1}$. No excess over expectations from Standard Model processes is observed. For models with exact left-right symmetry (the same coupling in the left and right sectors) we exclude the region in the two-dimensional parameter space that extends to ($M_{W_R}$, $M_{N_{\ell}}$) = (1700~GeV, 600~GeV).
