Light charged Higgs in the NMSSM

We review motivation for a light charged Higgs scenario that occurs in a class of models with a light CP-odd Higgs boson. If the light CP-odd Higgs is doublet-like the charged Higgs is typically lighter than the top quark and it dominantly decays into $W^{\pm }A$ with $B(H^{+}\to W^{+}A)>70$. We summarize experimental constraints from direct searches and discuss search strategies based on subleading decay modes of the CP-odd Higgs. A search for $t \to H^+ b, ;;;; H^+ \to W^+ A, ;;;; A \to \mu^+ \mu^- $ could provide an evidence for the charged Higgs or a discovery already with 1 fb${}^{-1}$ of data at the LHC.
