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. Upper limits at 95% confidence level are obtained on the combined branching fraction for the decay chain t $$\to$$ bH$^+$ $$\to$$ bW$^+$A $$\to$$ bW$$^+\mu^+\mu^-$$, of 1.9 $$\times$$ 10$$^{-6}$$ to 8.6 $$\times$$ 10$$^{-6}$$, depending on the masses of the H$^+$ and A bosons. These are the first limits for these decay modes of the H$^+$ and A bosons.
