Coherent photo-production of $\rho^0$ mesons in ultra-peripheral Pb-Pb collisions at the LHC measured by ALICE

We present the differential cross section for coherent rho^0 photo-production at mid-rapidity (-0.5 < y < 0.5) measured by the ALICE experiment in Pb-Pb collisions at s**(1/2)_NN = 2.76 TeV at the LHC, as well as the total rho^0 cross section obtained by modelbased extrapolation to all rapidities. These cross sections are compared to various model predictions, as well as to earlier measurements at RHIC. In addition, we present results on nuclear breakup in coincidence with coherent rho^0 photo-production.
