A search for heavy neutral Higgs bosons is performed using the LHC Run 2 data, corresponding
to an integrated luminosity of 139 fb−1 of proton-proton collisions at ffiffi
s p ¼ 13 TeV recorded with the
ATLAS detector. The search for heavy resonances is performed over the mass range 0.2–2.5 TeV for the
τþτ− decay with at least one τ-lepton decaying into final states with hadrons. The data are in good
agreement with the background prediction of the standard model. In the M125
h scenario of the minimal
supersymmetric standard model, values of tan β > 8 and tan β > 21 are excluded at the 95% confidence
level for neutral Higgs boson masses of 1.0 and 1.5 TeV, respectively, where tan β is the ratio of the vacuum
expectation values of the two Higgs doublets.
