Ultraperipheral lead-lead collisions at the LHC provide an intense flux of quasi-real photons. Collisions between these photons can yield the production of pairs of -leptons. This proceeding presents the first differential fiducial cross-section measurements of photon-induced di-tau production in lead-lead collisions at the LHC. The presented measurements utilise the full LHC Run 2 lead-lead dataset of 1. 93 nb^-1 recorded at s₍₍ = 5. 02 TeV by the ATLAS detector.
