Light charged Higgs boson with dominant decay to quarks and its search at LHC and future colliders

Abstract

The possibility of a light charged Higgs boson $H^{\pm }$ that decays predominantly to quarks ($cs$ and/or $cb$) and with a mass in the range 80 GeV $\le m_{H^{\pm }}\le 90$ GeV is studied in the context of Three-Higgs-Doublet Models (3HDMs). At present the Large Hadron Collider (LHC) has little sensitivity to this scenario, and currently the best constraints are from LEP2 and Tevatron searches. The branching ratio of $H^{\pm }\to cb$ can be dominant in two of the five types of 3HDM, and we determine the parameter space where this occurs. The decay $H^{\pm }\to cb$ has recently been searched for at the LHC for the first time, and with increased integrated luminosity one would expect sensitivity to the region 80 GeV $\le m_{H^{\pm }}\le 90$ GeV due to the smaller backgrounds with respect to $H^{\pm }\to cs$ decays.
