Abstract
The search for direct production of a heavy right-handed W<sub>R</sub> boson, which decays to a right-handed neutrino N<sub>l</sub>(l=e,μ), with a final state containing two same-flavor leptons and two jets, consistent with a left-right symmetric extension to the standard model, is presented. The search was conducted using the full 19.7 fb<super>-1</super> of proton-proton collision data collected at a center of mass energy of sqrt(s) = 8 TeV by the Compact Muon Solenoid detector at the Large Hadron Collider. No significant deviation from the standard model is observed in either channel. 95% confidence level exclusion limits in the plane of W<sub>R</sub> mass versus right-handed neutrino mass are set for the electron and muon channel that extends up to 3 TeV in W<sub>R</sub> mass and exclude most neutrino masses below the mass of the W<sub>R</sub>. The electron and muon channel data are also combined assuming degenerate right-handed neutrino masses. A brief discussion of the efforts to upgrade the readout electronics of the hadronic calorimeter of the Compact Muon Solenoid detector is also presented.
