Description

A new search for heavy charged Higgs bosons decaying to a pair of top and bottom quarks is performed using the full LHC Run-2 proton-proton data with the ATLAS detector. The search is performed using multi-jet final states with one electron or muon. Events are categorised according to the multiplicity of jets and how likely these are to have originated from hadronisation of a bottom quark. A mass-parameterised neural network is used to discriminate between signal and background events in four separate signal regions and simultaneously included in a maximum-likelihood fit to the data. Results are interpreted in the context of the hMSSM and Mh-125 scenario of the Minimal Supersymmetric Standard Model.
