Abstract:
Most of the current experimental searches for charged Higgs bosons ($H^\pm$) at the Large Hadron Collider (LHC) concentrate upon the $tb$ and $\tau\nu$ decay channels. In this talk, we analyze instead the feasibility of the bosonic decay channel $W^{\pm} h$, with $h$ being a neutral light Higgs boson. In the type-I two Higgs doublet model, where existing theoretical and experimental constraints still allow for light $H^\pm$ with a mass below the top quark mass, we consider the associated production of a charged Higgs with such a light neutral one, $pp\to H^\pm h$, at the LHC followed by the aforementioned charged Higgs boson decay. We specifically study $W^{\pm}+4b/4\gamma$ final states and prove that there is a strong possibility that these signals could be found at 14 TeV LHC and luminosity of 300 $\rm{fb}^{-1}$.
