"Dijet mass" of "Search for a light charged Higgs boson in $t \to H^\pm b$ decays, with $H^\pm \to cs$, in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"

Distributions of the dijet mass. The processes $t\bar{t}$(allHad), $tW$, Single top, $t\bar{t}H$, Other top, $W$ + jets, $Z$ + jets, and $VV$ listed are combined with the multijet background in the ‘Other’ category. The uncertainty band represents the combined statistical and systematic uncertainty of the prediction. Overlaid are the shapes for the $H^{\pm}_{80}$ and $H^{\pm}_{150}$ signal samples normalised to the total background prediction.
