$\gamma\gamma \rightarrow e^+ e^-$ cross section (blue circles) for ultra-peripheral Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}} } = 2.76$ TeV at $-0.9< \eta< 0.9$ for events in the invariant mass interval $2.2< M_{\rm inv}< 2.6$ GeV/$c^{2}$ (top) and $3.7< M_{\rm inv}< 10$ GeV/$c^{2}$ interval (bottom) compared to STARLIGHT simulation (black line). The blue(green) bars show the statistical (systematic) errors, respectively.
