$\gamma\gamma \to \gamma \gamma$ scattering in ultrarelativistic UPC [PDF]

Proceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2017), 2017
We discuss diphoton semi(exclusive) production in ultraperipheral lead-lead collisions at energy of $\sqrt{s_{NN}}$ = 5.5 TeV (LHC) and in proton-proton collisions at $\sqrt{s_{pp}}$ = 7 TeV (LHC) and $\sqrt{s_{pp}}$ = 100 TeV (FCC).
