Description

This talk reports the observation of $\tau$-lepton pair production in ultraperipheral lead-lead collisions and a measurements of for the $\tau$-lepton anomalous magnetic moment, $a_{\tau}$. The dataset corresponds to an integrated luminosity of 1.44/nb of Pb+Pb collisions at 5.02 TeV recorded by the ATLAS experiment in 2018.
