"Figure 6 (left plot): cross section limits" of "Search for long-lived particles decaying into displaced jets in proton-proton collisions at $\sqrt{s} =$ 13 TeV"

the expected and observed $95%$ $\text{CL}$ upper limits on the pair production cross section of the long-lived top squark, assuming a $100%$ branching fraction for $\widetilde{\mathrm{t}}\to\mathrm{b}\ell$ decays.
