Probing two-photon decay widths of mesons at energies available at the CERN Large Hadron Collider (LHC)

Abstract

Meson production cross sections in ultra-peripheral relativistic heavy ion collisions at LHC 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.
