Search for new gauge bosons and right-handed Majorana neutrinos in $pp$ collisions at $\sqrt{s}$~=~14 TeV

In the theoretical framework of the Left-Right Symmetric Model, we report on the discovery potential for new charged gauge bosons ($W_{R}^{+}$ and $W_{R}^{-}$) as well as right-handed Majorana neutrinos ($N_{l}$) at the future LHC. The $pp \rightarrow W_{R} \rightarrow l N_{l}$ signals have been simulated in the ATLAS detector. Discovery contours in the $(m_{W_{R}},m_{N_{e}})$ plane as well as a study of polarization effects are presented.
