      abstract     = {This Letter reports the first measurement of photonuclear
                      D$^0$ meson production in ultraperipheral heavy ion
                      collisions. The study is performed using lead-lead collision
                      data, with an integrated luminosity of 1.38 nb$^{-1}$,
                      collected by the CMS experiment at a nucleon-nucleon
                      center-of-mass energy of 5.36 TeV. Photonuclear events,
                      where one of the colliding nuclei breaks up and the other
                      remains intact, are selected based on breakup neutron
                      emissions and by requiring no particle activity in a large
                      rapidity interval in the direction of the photon-emitting
                      nucleus. The D$^0$ mesons are reconstructed via the
                      D$^0$$\to$ K$^-$$π^+$ decay channel, with the cross section
                      measured as a function of D$^0$ meson transverse momentum
                      and rapidity. The results are compared with
                      next-to-leading-order perturbative QCD calculations that
                      employ recent parametrizations of the lead nuclear parton
                      distribution functions, as well as with predictions based on
                      the color glass condensate framework. This measurement is
                      the first photonuclear collision study characterizing parton
                      distribution functions of lead nuclei for parton fractional
                      momenta $x$ (relative to the nucleon) ranging approximately
                      from a few 10$^{-4}$ to 10$^{-2}$ for different hard energy
                      scale $Q^2$ selections.},
