"Figure 10d: Postfit $m_\mathrm{vis}$ distribution in tautau" of "Observation of $\gamma\gamma\to\tau\tau$ in proton-proton collisions and limits on the anomalous electromagnetic moments of the $\tau$ lepton"

Observed and predicted $m_\mathrm{vis}$ distributions in the $\tau_\mathrm{h}\tau_\mathrm{h}$ final state for events with $N_\mathrm{tracks} = 1$. The normalization of the predicted background distributions corresponds to the result of the global fit. The signal distribution is normalized to its best fit signal strength. The uncertainty band accounts for all sources of background and signal uncertainty, systematic as well as statistical, after the global fit.
