title: "Supplementary Figure 2: 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 (post-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).
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.

description: A search is presented for non-resonant Higgs boson pair production, targeting the bbZZ, 4V(V= W or Z),VV$\tau\tau$, 4$\tau$, $\gamma\gamma$VV and $\gamma\gamma\tau\tau$ decay channels. Events are categorised based on the multiplicity of light charged leptons (electrons or muons), hadronically decaying tau leptons, and photons. The search is based on a data sample of proton--proton collisions at $\sqrt{s}$ = 13 TeV recorded with the ATLAS detector during Run 2 of the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb$^{-1}$. No evidence of the signal is found and the observed (expected) upper limit on the cross-section for non-resonant Higgs boson pair production is determined to be 17 (11) times the Standard Model predicted cross-section at 95% confidence level under the background-only hypothesis. The observed (expected) constraints on the HHH coupling modifier, $\kappa_{\lambda}$, are determined to be -6.2 &lt; $\kappa_{\lambda}$ &lt; 11.6 (-4.5 &lt; $\kappa_{\lambda}$ &lt; 9.6) at 95% confidence level,assuming the Standard Model for the expected limits and that new physics would only affect $\kappa_{\lambda}$.
