"Figure 9f" of "Search for W' bosons decaying to a top and a bottom quark in leptonic final states in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

Observed 95% CL upper limit on the production cross section for a generalized left-right coupling of the W' boson to a t and a b quark for a mass of the W' boson of 6 TeV.

针对W'玻色子（W' boson）质量为6太电子伏特（TeV）的情形，该粒子与顶夸克（t quark）、底夸克（b quark）之间的广义左右手耦合所对应的产生截面的观测95%置信度上限。
