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 → WR±\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ {W}_R^{\pm } $$\end{document} → e±N → e±e±jj process can be expanded upon considering an additional channel mediated by the right-handed doubly charged Higgs δR±±\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ {\delta}_R^{\pm \pm } $$\end{document}, i.e. pp → WR±\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ {W}_R^{\pm } $$\end{document} → WR∓∗δR±±∗\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ {W}_R^{\mp \ast }{\delta}_R^{\pm \pm \ast } $$\end{document} → e±e±jj.
