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 of the Large Hadron Collider (LHC). We use its framework to investigate the lepton number violating process pp → e±e±jj + X at the 14 TeV LHC. We show that for an integrated luminosity of 300 fb−1, the discovery contour of the right-handed boson WR and the right-handed electron neutrino Ne as a result of the pp → $$ {W}_R^{\pm } $$ W R ± → e±N → e±e±jj process can be expanded upon considering an additional channel mediated by the right-handed doubly charged Higgs $$ {\delta}_R^{\pm \pm } $$ δ R ± ± , i.e. pp → $$ {W}_R^{\pm } $$ W R ± → $$ {W}_R^{\mp \ast }{\delta}_R^{\pm \pm \ast } $$ W R ∓ ∗ δ R ± ± ∗ → e±e±jj.
