A search for charged Higgs bosons heavier than the top quark and decaying
via H± → tb is presented. The data analysed corresponds to 36.1 fb⁻¹ of pp collisions at
√s = 13 TeV and was recorded with the ATLAS detector at the LHC in 2015 and 2016.
The production of a charged Higgs boson in association with a top quark and a bottom
quark, pp → tbH±, is explored in the mass range from mH± = 200 to 2000 GeV using
multi-jet final states with one or two electrons or muons. Events are categorised according
to the multiplicity of jets and how likely these are to have originated from hadronisation
of a bottom quark. Multivariate techniques are used to discriminate between signal and
background events. No significant excess above the background-only hypothesis is observed and exclusion limits are derived for the production cross-section times branching ratio of a charged Higgs boson as a function of its mass, which range from 2.9 pb at mH± = 200 GeV to 0.070 pb at mH± = 2000 GeV. The results are interpreted in two benchmark scenarios of the Minimal Supersymmetric Standard Model.
