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→bH+→bW+A→bW+μ+μ-, of 1.9×10-6 to 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 A bosons. ? 2019 CERN.Decay (organic); Germanium compounds; Branching fractions; CMS detectors; Confidence levels; Decay chains; Higgs boson; Integrated luminosity; Proton proton collisions; Upper limits; Bosons; article; boson; luminance; quarkjournal article10.1103/PhysRevLett.123.131802316975162-s2.0-85072809360
