Exploring the doubly charged Higgs boson of the left-right symmetric model using vector boson fusionlike events at the LHC

Abstract

This paper studies the pair production of the doubly charged Higgs boson of the left-right symmetric model using a multilepton final state in the vector boson fusionlike processes. The study is performed in a framework consistent with the model's correction to the standard model ${\ensuremath{\rho}}_{\mathrm{EW}}$ parameter. Vector boson fusion topological cuts, the number of leptons, and ${p}_{T}$ cuts on the leptons are found to be effective in suppressing the background. Significant mass reach can be achieved for exclusion/discovery of the doubly charged Higgs boson for the upcoming LHC run with a luminosity of $\mathcal{O}(1{0}^{3})\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$.
