Search for heavy neutral Higgs bosons decaying into a top quark pair in 140 fb−1 of proton-proton collision data at √s = 13 TeV with the ATLAS detector
A search for heavy pseudo-scalar (A) and scalar (H) Higgs bosons decaying into a top-quark pair (tt¯) has been performed with 140 fb−1 of proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider at a centre-of-mass energy of s = 13 TeV. Interference effects between the signal process and Standard Model (SM) tt¯ production are taken into account. Final states with
