Extending the Standard Model (SM) scalar sector via the addition of one or more Higgs fields in higher dimensional representations adds one or more charged Higgs bosons to the spectrum. Some of these gauge representations with appropriate hypercharge contain doubly-charged Higgs bosons and can be easily distinguished from the models that contain only singly-charged Higgs bosons. In this study we focus on the more challenging question of distinguishing singly-charged Higgs bosons from different representations, viz. doublets and triplets of the SU(2)(L) gauge group. We consider a supersymmetric extension of the SM with a gauge singlet and an SU(2)(L) triplet with Y = 0 as a benchmark scenario which has rich phenomenological possibilities due to the presence of a light pseudoscalar associated with the Z(3) symmetric superpotential. A detailed collider simulation considering all SM backgrounds has been carried out in order to determine which final states are more favourable for observing charged Higgs boson from particular representations as compared with others. We show that different representations can be probed and distinguished via singly-charged Higgs boson phenomenology at the 14TeV LHC with an earliest data of similar to 50 fb(-1) of integrated luminosity.
