| Abstract: A search for a light charged Higgs boson ($\mathrm{H}^{+}$) decaying to a W boson and a CP-odd Higgs boson (A) is performed using data from proton-proton collisions at $\sqrt{s}= $ 13 TeV. The data were recorded by the CMS detector at the LHC in 2016 and correspond to an integrated luminosity of 35.9 fb$^{-1}$. In this search, it is assumed that the $\mathrm{H}^{+}$ boson is produced in decays of top quarks, and the A boson decays to two opposite-charge muons. The presence of signals for $\mathrm{H}^{+}$ 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 $\mathrm{H}^{+}$ boson is found. Assuming branching ratios $\mathcal{B}(\mathrm{H}^{+}\to\mathrm{W}^{+}\mathrm{A})=$ 1 and $\mathcal{B}(\mathrm{A}\to\mu^{+}\mu^{-})=3\times10^{-4}$, upper limits at 95% confidence level on the branching fraction of the top quark, $\mathcal{B}(\mathrm{t}\to\mathrm{b}\mathrm{H}^{+})$, of 0.63 to 2.9% are obtained, depending on the masses of the $\mathrm{H}^{+}$ and A bosons. | ||
