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

Abstract

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 } → 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 } , i.e. pp → {W}_R^{pm } → {W}_R^{mp ast }{delta}_R^{pm pm ast } → e±e±jj.
