"Figure 5" of "Search for a heavy resonance decaying into a Z and a Higgs boson in events with an energetic jet and two electrons, two muons, or missing transverse momentum in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

Expected upper limits at 95% CL on the product of the production cross section and the branching fraction as a function of the Z' boson mass.Each line corresponds to the three different final states and their combined result.

针对以Z'玻色子（Z' boson）质量为自变量的产生截面与分支比的乘积，给出其95%置信度（Confidence Level, CL）下的预期上限。每一行对应三种不同的末态及其联合结果。
