Experimental overview on UPC results at STAR.
The ALICE Collaboration has extensively studied coherent and incoherent J/$\psi$ photoproduction, as well as coherent $\psi$' in ultra-peripheral Pb-Pb collisions using the Run 2 data set, including results from exclusive and dissociative J/$\psi$ mesons in ultra-peripheral p-Pb interactions, together also with the |t|-dependence of (in)coherent J/$\psi$. These measurements, which studied...
Exclusive processes in high energy collisions can be described in terms of either a collinear factorization or a dipole approach. While these approaches have a common limit, they also differ in many ways. For example one can consider it more important to resum large logarithms of either transverse or longitudinal momenta. There can also be different views about whether the dominant transverse...
I will present an overview on the topic of Monte Carlo event generators for UPCs and photon-mediated processes
We will present an overview of theoretical and phenomenological studies on the partonic structure of nuclei and small-x dynamics of QCD using photon-nucleus scattering in UPCs. In particular, we review implications of exclusive charmonium and inclusive dijet production in Pb-Pb UPCs at the LHC as well as discuss the potential of new measurements of diffractive dijet and inclusive heavy quark...
Over the last years, several authors have demonstrated that the study of exclusive processes in hadronic collisions provides new possibilities for the investigation of the Quantum Electrodynamics and Quantum Chromodynamics at high energies, as well as to searching for Beyond the Standard Model (BSM) Physics. In this talk, I will review the recent predictions for the production of new particles...
I will review the status of our understanding of collectivity in ultra peripheral heavy ion and p+A collisions.
