##### Search for a light charged Higgs boson decaying to a W boson and a CP-odd Higgs boson in final states with e$μμ$ or $μμμ$ in proton-proton collisions at $\sqrt{s}=$ 13 TeV
A search for a light charged Higgs boson (H$^+$) decaying to a W boson and a CP-odd Higgs boson (A) in final states with e$\mu\mu$ or $\mu\mu\mu$ is performed using data from pp collisions at $\sqrt{s}=$ 13 TeV, recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 35.9 fb$^{-1}$. In this search, it is assumed that the H$^+$ boson is produced in decays of top quarks, and the A boson decays to two oppositely charged muons. The presence of signals for H$^+$ boson masses between 100 and 160 GeV and A boson masses between 15 and 75 GeV is investigated. No evidence for the production of the H$^+$ boson is found. Assuming branching fractions $\mathcal{B}$(H$^+ \to$ W$^+$A) $=$1 and $\mathcal{B}$(A $\to \mu\mu$)$=$ 3 $\times$ 10$^{-4}$, upper limits at 95% confidence level on the branching fraction of the top quark, $\mathcal{B}$(t $\to$ bH$^+$), of 0.63 to 2.9% are obtained, depending on the masses of the H$^+$ aund A bosons. These are the first limits on $\mathcal{B}$(t $\to$ bH$^+$) in the decay mode of the H$^+$ boson: H$^+$ $\to$ W$^+$A $\to$ W$^+\mu^+\mu^-$.
