"VR kinematics 2" of "Search for direct top squark pair production in final states with two leptons in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector"

Two-body selection distribution of $m_{T2}^{ll}$ for events satisfying all the VR$^{2-body}_{t\bar{t}}$ selections, after the background fit. The contributions from all SM backgrounds are shown as a histogram stack; the bands represent the total statistical and systematic uncertainty. The rightmost bin of each plot includes overflow events.
