Abstract
Exclusive vector meson photoproduction is studied in ultra-peripheral pPb collisions at $\sqrt{s_{NN}} = 5.02$ TeV. The cross sections are measured as a function of the photon-proton centre-of-mass energy, extending the energy range explored by H1 and ZEUS Experiments at HERA. In addition, the differential cross sections ($d\sigma/d|t|$), where $|t|\approx p^{2}_{T}$ is the squared transverse momentum of produced vector mesons, are measured and the slope parameters are obtained. The results are compared to previous measurements and to theoretical predictions.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating very compact bibliographies which can be beneficial to authors and readers, and in "proceeding" format which is more detailed and complete.
