Title: Search for a light charged Higgs boson decaying to a W boson and a CP-odd Higgs boson in final states with e$$\mu\mu$$ or $$\mu\mu\mu$$ in proton-proton collisions at $$\sqrt{s}=$$ 13 TeV

Abstract

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$$^+\mu^+\mu^-$$.
