Description
Open heavy-flavor production in ultraperipheral collisions (UPCs) enables the study of cold nuclear matter over a wide range of momentum transfers $Q$ and parton momentum fractions $x$, without significant final-state effects. In this talk we present the final results for the first measurement of $\mathrm{D}^0$ photoproduction in heavy-ion UPCs using data collected by the CMS experiment during 2023 PbPb collisions at the LHC. The measured production cross sections are shown as a function of the $\mathrm{D}^0$ transverse momentum, $2\lt p_{T}\lt12$ GeV/c and rapidity, $\eta \lt$ -2.
