"Figure 16b from Auxiliary material" of "Search for ttbar resonances in final states with exactly one or two leptons using 140 fb$^{-1}$ of pp collision data at $\sqrt{s}=13$ TeV with the ATLAS experiment"
Abstract
Two-dimensional plots of the tt̄ invariant mass at reconstruction level, mtt, against the tt̄ invariant mass at the parton level before the emission of FSR, mt̄tbefore FSR, for the SM tt̄ background in (a) the Resolved 1b, (b) the Resolved 2b, and (c) the Merged signal regions of the 1-lepton channel. The colour scale indicates the total number of events in each bin.
