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 $pp\to e^{\pm }{e}^{\pm }jj+X$ at the $\text{unit}[14]TeV$ LHC. We show that for an integrated luminosity of $\text{unit}[300]f{b}^{-1}$, the discovery contour of the right-handed boson $W_R$ and the right-handed electron neutrino $N_e$ as a result of the $pp\to W_R^{\pm }\to e^{\pm }N\to e^{\pm }{e}^{\pm }jj$ process can be expanded upon considering an additional channel mediated by the right-handed doubly charged Higgs ${\delta }_R^{\pm \pm }$, i.e. $pp\to W_R^{\pm }\to W_R^{\mp \ast }{\delta }_R^{\pm \pm \ast }\to e^{\pm }{e}^{\pm }jj$.
