  Extending the Standard Model (SM) scalar sector via one or multiple Higgs
field(s) in higher representation brings one or more charged Higgs bosons in
the spectrum. Some of these gauge representations with appropriate hypercharge
can bring up doubly charged Higgs boson and can be easily distinguished from
the existing models with only singly charged Higgs boson. In this study we
focus on distinguishing the singly charged Higgs bosons from different
representations, viz. doublets and triplets of $SU(2)_L$ gauge group. We
consider a supersymmetric extension of SM with a gauge singlet and $SU(2)_L$
triplet with $Y=0$ as a benchmark scenario with the possibility of rich
phenomenology due to existence of light pseudoscalar for $Z_3$ symmetric
superpotential. A detailed collider simulation considering all the SM
backgrounds has been carried out in order to classify the final states which
are favourable to charged Higgs boson from one particular representation than
others. We show that such different representations can be probed an
distinguished via looking at single charged Higgs boson phenomenology at the
LHC with 14 TeV center of mass energy within $\sim 50$ fb$^{-1}$ of integrated
luminosity.
