Charged Higgs in Beyond the Minimal Supersymmetric Standard Model at the LHC

Abstract

The charged Higgs boson is an inevitable particle in supersymmetric models, both in the minimal version and in extensions. It is also a particle, which may have different decay channels depending on the scalar representations in the model, and thus it may help in identifying the model. In this talk I will consider the simplest singlet and triplet extensions of the minimal supersymmetric standard model, and in particular, describe some smoking gun signals of charged Higgs at the LHC collider. I will also comment the charged scalars in a supersymmetric left-right model.
