Abstract
The possibility of a light charged Higgs boson that decays predominantly to a charm quark and a bottom quark () and with a mass in the range is studied in the context of a three-Higgs doublet model (3HDM). Searches for this decay at the Large Hadron Collider do not have sensitivity to this mass region at present. It is shown that the searches for at LEP2 could be supplemented by either one or two -tags, which would enable such large branching ratios for to be probed in the above mass region. We comment on the possibility of this 3HDM scenario to explain a slight excess in the searches for at LEP2, which is best fit by of around 90 GeV, and discuss the prospects for detecting decays at future colliders.
