A search is presented for charged Higgs bosons in the H± → τ
±
ντ 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−1
.
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
τ
±
ντ
for an H±
in the mass range of 80 GeV to 3 TeV, 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
mod−
h
scenario
