Description
The Two Higgs Doublet Model (2HDM) is one of the simplest extensions to the Standard Model Higgs sector, and predicts the existence of additional Higgs bosons, including a pair of charged Higgs bosons $H^\pm$ and a pseudoscalar Higgs boson $A$. Existing searches for the charged Higgs mostly focus on the $H^\pm\rightarrow\tau\nu /cs$ decay channels. For light $A$’s, $H^\pm\rightarrow AW$ becomes kinematically accessible and competitive with the conventional channels. We examine the single top production channel with $t\rightarrow bH^\pm$, and the subsequent decay chain of $H^\pm\rightarrow AW\rightarrow\tau\tau l\nu$. We perform a collider analysis and obtain exclusion and discovery reach at the 14 TeV LHC with 100 fb−1 integrated luminosity. We further study the implication of the search limits on the Type II 2HDM.
