Potential to observe new physics signatures at the LHC with 300 fb^{-1} luminosity.

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