"Expected and observed limits on $\sigma$ x $\mathcal{B}$ x $A$" of "Search for a narrow resonance lighter than 200 GeV decaying to a pair of muons in proton-proton collisions at $\sqrt{s} =$ 13 TeV"

Expected and observed upper limits at 95% CL on the product of the signal cross section ($\sigma$) for a narrow resonance, branching fraction to a pair of muons ($\mathcal{B}$), and acceptance ($A$) as a function of the mass of a narrow resonance. Results obtained using the scouting (standard) triggers are to the left (right) of the vertical purple line.
