Abstract: | A search for a light charged Higgs boson (H+) decaying to a Wboson and a CP-odd Higgs boson (A) in final states with eμμor μμμis performed using data from ppcollisions at √s=13 TeV, recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 35.9fb−1. In this search, it is assumed that the H+ boson is produced in decays of top quarks, and the Aboson 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→bH+→bW+A→bW+μ+μ−, of 1.9×10−6to 8.6×10−6, depending on the masses of the H+ and A bosons. These are the first limits for these decay modes of the H+and Abosons. |
