Description
The center-of-mass energies available at modern accelerators, such as the Large Hadron Collider (LHC), and at future generation accelerators, such as the Electron-Ion Collider (EIC) and Future Circular Collider (FCC), offer us a unique opportunity to investigate hadronic matter under the most extreme conditions ever reached. One of the most intriguing phenomena of strong interaction is the so-called gluon saturation in nucleons and nuclei. In the saturation regime, the density of partons, per unit transverse area, in hadronic wavefunctions becomes very large leading to non-linear effects, that are described by the Balitsky-JIMWLK hierarchy of equations.
Pursuing the goal of obtaining accurate theoretical predictions to test the physics of saturation, we compute the cross-sections of diffractive single and double hadron photo- or electroproduction with large $p_T$, on a nucleon or a nucleus at next-to-leading logarithmic accuracy. We employ a hybrid formalism mixing collinear factorization and high energy small-$x$ factorization. This new class of processes provides an access to precision physics of gluon saturation dynamics, with very promising future phenomenological studies at the EIC, or, at the LHC in $p A$ and $A A$ scattering, using Ultra Peripheral Collisions (UPC).
