Description

Perturbative Quantum Chromodynamics describes the strong interaction among quarks and gluons. Specifically, the gluons are supposed to recombine at low momentum (low x) for extreme conditions, onseting saturation to restore unitarity. This challenging phenomenon is faced experimentally with peripheral and ultraperipheral production of heavy mesons, J/Psis and Upsilons, mostly gluons dependent. The modelling for photoproduction considering different event geometries, at distinct classes of centrality, for cross sections distributions on energy, transverse momentum, rapidity are presented, compared with data with good agreement for pp, pA, and AA. Simulations for FoCal (ALICE) and its capabilities to distinguish each heavy meson for new kinematical limits are also shown.
