ABSTRACT We study the production of spin-one mesons in high-energy heavy-ion
collisions with peripheral kinematics in the framework of QED. The cross
sections of the production of a single vector meson and of two different ones
are presented. The explicit dependence on the virtuality of the intermediate
vector meson is obtained within a quark model. The effect of reggeization of
the intermediate vector meson state in the case of the production of two vector
mesons is taken into account.

• Article: Coherent photoproduction of ψ and Υ mesons in ultraperipheral pPb and PbPb collisions at the CERN Large Hadron Collider at √sNN=5 TeV and √sNN=2.76 TeV
[Hide abstract]
ABSTRACT: Exclusive photoproduction of vector mesons in the perturbative two-gluon exchange formalism depends significantly on nucleon and nuclear gluon distributions. In the present study we calculate total cross sections and rapidity distributions of J/ψ(1s), ψ(2s), Υ(1s), Υ(2s), and Υ(3s) in ultraperipheral proton-lead (pPb) and lead-lead (PbPb) collisions at the CERN Large Hadron Collider (LHC) at √sNN=5 TeV and √sNN=2.76 TeV, respectively. Effects of gluon shadowing are investigated and potentials for constraining nuclear gluon modifications are discussed.
