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

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 rho(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 O(10(3)) fb(-1).
