Majorana Neutrino and W_(R) at TeV scale ep Colliders

Production of heavy Majorana neutrino $N_{e}$ predicted by left-right symmetric extension of the Standard Model at future {\normalsize TeV} scale $ep$ colliders have been considered. In order to estimate potential of $ep$ colliders for $N_{e}$ search we consider back-groundless process $e^{-}p\rightarrow e^{+}X$ which is consequence of Majorana nature of $N_{e}$. It is shown that {\normalsize linac-LHC} and {\normalsize linac-FCC} based $ep$ colliders will cover much wider regions of $N_{e}$ and $W_{R}$ masses than corresponding linear electron-positron colliders.
