Introduction
Figure 1
Figure from https://xkcd.com/2440. In CMS, the
epistemic uncertainty is perhaps “how many unknown bugs did I introduce
in my code?”

Figure 3
Distributions of \(m_{t\bar{t}}\) in the single-lepton signal
regions of the 2016 \(Z'\) search
that had 1 or more top-tagged jets. Figure from https://arxiv.org/pdf/1810.05905.
