Description
High energy photons originating from the electromagnetic field of ultrarelativistic lead nuclei can interact with the other lead beam. These reactions are studied in the ultra-peripheral heavy ion collisions to probe the physics of strong interactions. The analysis of dipion and dikaon photoproduction was carried out using the ALICE 2015 Pb-Pb data at center-of-mass energy $\sqrt{s_{NN}}=5.02$ TeV. We will be presenting the $\rho^0$ meson and direct $\pi^+\pi^-$ measurements, as well as the prospects of studying exclusive $K^+K^-$ photoproduction, with sensitivity towards higher dikaon invariant mass above the $\phi(1020)$ threshold.
