Detection of heavy Majorana neutrinos and right-handed bosons

The SUc(3) - SUL(2) - SUR(2) - U(1) left-right (LR) symmetric model explains the origin of the parity violation in weak interactions and predicts the existence of additional gauge bosons WR and Z'. In addition, heavy right-handed Majorana neutrino states N arise naturally within the LR symmetric model. The states N could be partners of light neutrino states, related to their nonzero masses through the seesaw mechanism. This makes the searches for WR, Z', and N interesting and important. In the framework of the minimal LR model, we study the possibility to observe signals from N and WR production in pp collisions after three years of running at low LHC luminosity. We show that their decay signals can be identified with a small background, especially in the case of same-sign leptons in the final state. For the integral LHC luminosity of Lt = 30 fb-1, the 5σ discovery of WR boson and heavy Majorana neutrinos Ne with masses MWR up to 4 TeV and MNe up to 2.4 TeV, respectively, is found to be possible
