"Fig. 3: Exclusion limit (DM mediator)" of "Measurement of dijet angular distributions and search for beyond the standard model physics in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

The 95% CL upper limits on the universal quark coupling $g_{q}$ as a function of a vector or axial-vector mediator mass, with $g_{DM}=1.0$ and $m_{DM}=1$ GeV. The observed and expected limits and their variation at the 1 and 2 standard deviation levels are given.
