1. Nucleon dissociation and incoherent J/ψ photoproduction on nuclei in ion ultraperipheral collisions at the CERN Large Hadron Collider / Guzey, V. ; Strikman, M. ; Zhalov, M.
Using the general notion of cross section fluctuations in hadron-nucleus scattering at high energies, we derive an expression for the cross section of incoherent J/ψ photoproduction on heavy nuclei dσγAJ/ψY/dt, which includes both elastic dσγpJ/ψp/dt and proton-dissociation dσγpJ/ψY/dt photoproduction on target nucleons.

5. Mapping color fluctuations in the photon in ultraperipheral heavy ion collisions at the Large Hadron Collider / Alvioli, M. ; Frankfurt, L. ; Guzey, V. ; Strikman, M. ; et al
We model effects of color fluctuations (CFs) in the light-cone photon wave function and for the first time make predictions for the distribution over the number of wounded nucleons ν in the inelastic photon–nucleus scattering. [...]

6. A fresh look at factorization breaking in diffractive photoproduction of dijets at HERA at next-to-leading order QCD / Guzey, V. ; Klasen, M.
We calculate the cross section of diffractive dijet photoproduction in ep scattering at next-to-leading order (NLO) of perturbative QCD (pQCD), which we supplement by a model of factorization breaking for the resolved-photon contribution. [...]

8. Nuclear shadowing in photoproduction of ρ mesons in ultraperipheral nucleus collisions at RHIC and the LHC / Frankfurt, L. ; Guzey, V. ; Strikman, M. ; Zhalov, M.
We argue that with an increase of the collision energy, elastic photoproduction of ρ mesons on nuclei becomes affected by the significant cross section of photon inelastic diffraction into large masses, which results in the sizable inelastic nuclear shadowing correction to σγA→ρA and the reduced effective ρ -nucleon cross section.

9. Disentangling coherent and incoherent quasielastic J/ψ photoproduction on nuclei by neutron tagging in ultraperipheral ion collisions at the LHC / Guzey, V. ; Strikman, M. ; Zhalov, M.
We consider J/ψ photoproduction in ion–ion ultraperipheral collisions (UPCs) at the LHC and RHIC in the coherent and incoherent quasielastic channels with and without accompanying forward neutron emission and analyze the role of nuclear gluon shadowing at small x ,  x=10-4-10-2 , in these processes.
