Search for like-sign dileptons plus two jets signal in the framework of the manifest left-right symmetric model

The left-right symmetric model may present evidence of new physics at the era Large Hadron Collider (LHC). We use its framework to investigate lepton number violating process $pp \to e^\pm jj+X$ $\unit[14]{TeV}$ LHC. show that for an integrated luminosity $\unit[300]{fb^{-1}}$, discovery contour right-handed boson $W_R$ and electron neutrino $N_e$ as a result W^\pm_R N jj$ can be expanded upon considering additional channel mediated by doubly charged Higgs $\delta^{\pm\pm}_R$, i.e. $pp\to W^{\mp*}_R \delta^{\pm\pm*}_R jj$.
