Meson production cross sections in ultraperipheral relativistic heavy ion collisions at the CERN Large Hadron Collider are revisited. The relevance of meson models and of exotic QCD states is discussed. This study includes states that have not been considered before in the literature.

In ultra-peripheral relativistic nuclear collisions, the impact parameter is greater than the sum of the radii of the colliding nuclei. Hadronic interactions are suppressed in these collisions, but the intense flux of photons allows the study of photonuclear and two-photon interactions, providing information about the initial state of the nuclei. The STAR experiment has studied Au+Au...

In this talk, we will review the results by the CMS Collaboration in ultra-peripheral heavy-ion collisions (UPC). In particular, we will present and discuss the results on exclusive Rho0 and Upsilon photo production off the proton, and coherent J/psi photo production off the Pb target. Results on light-by-light scattering and in dijet photoproduction in ultra-peripheral PbPb collisions will...

Ultra-peripheral nucleus-nucleus collisions provide an opportunity to study nuclear parton distributions in a kinematic range not covered by previously existing measurements through measurements of jet photo-production. The ATLAS experiment at the LHC has carried out a set of measurements in 5.02 TeV ultra-peripheral Pb+Pb collisions including a measurement of light-by-light scattering, a...
