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

description: Observed and predicted $m_\mathrm{vis}$ distributions in the $\mathrm{e}\mu$ 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.
description: The photon-induced production of a pair of $\tau$ leptons, $\gamma\gamma\to\tau\tau$, is observed for the first time in proton-proton collisions. The observation is based on a data set recorded with the CMS detector at the LHC at a center-of-mass energy of $13~\mathrm{TeV}$ and corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$. Events with a small number of tracks close to the di-$\tau$ vertex are selected to isolate photon-induced processes. Limits on the anomalous electromagnetic moments of the $\tau$ lepton originating from potential new physics effects on the $\gamma\tau\tau$ vertex are also set.

title: "Figure 11: Postfit $N_\mathrm{tracks}$ distribution" of "Observation of $\gamma\gamma\to\tau\tau$ in proton-proton collisions and limits on the anomalous electromagnetic moments of the $\tau$ lepton"

description: Observed and predicted $N_\mathrm{tracks}$ distributions for events passing the SR selection but with the relaxed requirement $N_\mathrm{tracks} &lt; 10$ and the additional requirement $m_\mathrm{vis}&gt;100\,\mathrm{GeV}$, combining all the final states together. The acoplanarity requirement $A &lt; 0.015$ is applied. The inclusive diboson background contribution is drawn together with the ttbar process. The predicted distributions are adjusted to the result of the global fit performed with the mvis distributions in the SRs, and the signal distribution is normalized to its best fit signal strength. The lower panel shows the difference between the observed events and the backgrounds, as well as the signal contribution. Systematic uncertainties are assumed to be uncorrelated between final states to draw the uncertainty band.

title: "Supplementary Figure 1: Pileup track corrections" of "Observation of $\gamma\gamma\to\tau\tau$ in proton-proton collisions and limits on the anomalous electromagnetic moments of the $\tau$ lepton"

description: Event weights applied to simulations in the 2016 (pre-VFP) data-taking period as a function of the dilepton vertex position along the $z$ axis and the pileup track multiplicity in a 0.1 cm-wide window around the dilepton vertex ($N_\mathrm{tracks}^\mathrm{PU}$), where VFP stands for preamplifier feedback bias corrections due to inefficiencies in the strip modules of the tracker during the 2016 data-taking period. This correction is derived as a ratio between data and Drell-Yan simulation in a sample of dimuon events with $|m_{\mu\mu}-m_\mathrm{Z}|&lt;15\,\mathrm{GeV}$ (see Fig. 3).
