Measurement of the impact-parameter dependent azimuthal anisotropy in coherent $\ddot{I}{}^0$ photoproduction in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV

ALICE Collaboration

This Letter presents the first measurement of the impact-parameter dependent angular anisotropy in the decay of coherently photoproduced $\ddot{I}{}^0$ mesons. The $\ddot{I}{}^0$ mesons are recons…
