Ultra-peripheral collisions at the LHC provide a unique opportunity to study photon-hadron interactions in the new kinematic regime. Recent ALICE results from Run 2 on J/psi photoproduction in ultra-peripheral p-Pb and Pb-Pb collisions provide stringent constraints on gluon saturation effects. ALICE measurements on the coherent rho photoproduction allow for the studies of QCD in the... -

A brief analysis of the development of elastic scattering models in the LHC era is presented and short overview of the results of the model
based on the analyticity of the scattering amplitude with taking into account the hadron structure for high energy hadron elastic scattering
{\rm $pp$, $p\bar{p}$, $pn$, $p\pi$ ($\sqrt{s}=3.6$ GeV up to $\sqrt{s}=13$ TeV ) }. The main... -

Abstract We investigate coherent photoproduction of light vector mesons in Pb–Pb ultraperipheral collisions using the color dipole approach. Our analysis incorporates the Glauber–Gribov formalism with a gluon shadowing correction modeled via an effective suppression factor RG. This factor is fitted to match experimental data from the... -

Physical Review C.104.045202 2. arXiv: 2503.09995
Abstract The photoproduction of Φ and J/ψ meson off the nucleon is investigated within a dynamical model approach based on a Hamiltonian which describes the reaction mechanisms of the Pomeron exchange, meson exchange, and direct Φ- or J/ψ-radiation terms. The final state interaction is described by the gluon-exchange and direct Φ- or...
