Description
According to quantum chromodynamics, at high energy, hadrons exhibit a dynamic equilibrium between gluon splitting and recombination, known as saturation. Diffractive photonuclear production of J/ψ vector mesons provides unique insights into the gluon distribution of hadrons. The Mandelstam-t variable, representing the momentum transfer, probes hadron structure within the impact-parameter plane, with different t ranges sensitive to gluon field dynamics at various spatial scales. In this talk, we will present new ALICE measurements on the energy dependence of incoherent photonuclear production of J/ψ mesons off lead ions across Mandelstam-$t$ intervals, testing gluon saturation models in an unprecedented way.
