We compute the gravitational form factors of various nuclei in the Skyrme model. Based on https://arxiv.org/abs/2304.05994
Exclusive processes in Ultra Peripheral Collisions (UPCs) at the LHC and in the future EIC will provide access to the spatial distribution of small-x partons in nuclei at high energies. In particular, the transverse momentum of the produced particle, such as vector meson, is Fourier conjugate to the impact parameter.
In this talk, we focus on vector meson production in UPCs and show how...
The ALICE Collaboration has studied photonuclear interactions in ultra-peripheral heavy-ion collisions to probe gluon dynamics of protons and nuclei in a new kinematic regime at the LHC.
Several new measurements will be presented, including the coherent J/ψ photoproduction cross section, measured as a function of the Mandelstam |t|, which provides constraints of models that consider the...
We studied polarisation-dependent exclusive J/ψ production in ultraperipheral heavy-ion collisions at RHIC and LHC energies and in eA collisions at EIC energies, in the framework of color glass condensate effective theory. The azimuthal averaged J/ψ production cross section measured by STAR and ALICE is accurately described by our calculation. We further predict significant cos 2ϕ and cos 4ϕ...
