The study uses $2.2$ nb$^{-1}$ of integrated luminosity collected in 2015 and 2018 at $\\sqrt{s_\\mathrm{NN}}=5.02$ TeV. Light-by-light scattering candidates are selected in events with two photons produced exclusively, each with transverse energy $E_{\\mathrm{T}}^{\\gamma} > 2.5$ GeV, pseudorapidity $|\\eta_{\\gamma}| < 2.37$, diphoton invariant mass $m_{\\gamma\\gamma} > 5$ GeV, and with small diphoton transverse momentum and diphoton acoplanarity.
