Search for charged Higgs bosons in the H± ? t ± ?t decay channel in proton-proton collisions at √s=13 TeV

Abstract

A search is presented for charged Higgs bosons in the H ? t? decay mode in the hadronic final state and in final states with an electron or a muon. The search is based on proton-proton collision data recorded by the CMS experiment in 2016 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb. The results agree with the background expectation from the standard model. Upper limits at 95% confidence level are set on the production cross section times branching fraction to t? for an H in the mass range of 80GeV to 3TeV, including the region near the top quark mass. The observed limit ranges from 6 pb at 80 GeV to 5 fb at 3 TeV. The limits are interpreted in the context of the minimal supersymmetric standard model m scenario.[Figure not available: see fulltext.].
