Description

Ultraperipheral lead-lead collisions at $\sqrt{s_{_{\mathrm{NN}}}} = 5.02$ TeV produce very large photon fluxes that fundamental quantum-mechanical processes can be observed. In this presentation, the first observation of the $\tau$ lepton production in ultraperipheral PbPb collision data collected by CMS at LHC is reported. This measurement paves the way for the determination of the anomalous electromagnetic moments of the $\tau$ lepton, which currently is poorly constrained.
