$\rho$ photoproduction in ALICE

Abstract

The ${\rho }^0$ is copiously photoproduced in ultra-peripheral heavy-ion collisions at the LHC. In this talk, I will present recent results on $\rho$ photoproduction with ALICE, including cross-section measurements from PbPb and XeXe collisions, including a discussion of the production of high-mass final states that decay to ${\pi }^{+}{\pi }^{-}$, and of neutron production that accompanies $\rho$ photoproduction. I will conclude by presenting some prospects for ALICE in Runs 3 and 4.
