"Medium-NN score SR 1b lvbb postfit" of "Search for a heavy charged Higgs boson decaying into a $W$ boson and a Higgs boson in final states with leptons and $b$-jets in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector"

The mWh distributions in the Medium-NN-score SRs of the merged lvbb 1b event categories. The term ‘Others’ summarises events from tHjb, tWh, tttt, and SM Vh production. The background prediction is shown after a background-only maximum-likelihood fit to data. The individual background uncertainty does not take into account the possible correlations between the nuisance parameter. The expected signal contributions assuming $m_{H^{\pm}}$ = 900 GeV and $m_{H^{\pm}}$ = 2000 GeV, normalised the expected limit of the cross-section times branching ratio ($\sigma_{sig}$ × B) values of 0.036 pb and 2.7 fb respectively, are shown as dashed histograms.
