Exclusive diffractive meson production represents a promising channel for investigating gluonic saturation inside nucleons and nuclei. I’ll discuss a systematic framework to deal with beyond leading power corrections at small-x, including the saturation regime, and obtain the γ∗ → M(ρ, φ, ω) impact factor with both incoming photon and outgoing meson carrying arbitrary polarizations. This is...
In recent years, numerous studies have aimed at improving the precision of the theoretical description of the nonlinear QCD regime of gluon saturation in high-energy collisions, in order to match the precision of the data coming from the LHC and the future EIC. In particular, NLO QCD corrections have been calculated for many high-energy processes sensitive to gluon saturation.
In most of...
Derivation of finite energy corrections to high energy eikonal scattering processes within the Color Glass Condensate (CGC) effective theory has been a prominent topic over the last decade. In this talk, we will give a brief overview of next-to-eikonal corrections to parton propagators and their applications to various observables.
Instabilities in the non-linear evolution equation for gluon distributions in the saturation regime when approaching collinear kinematics were noticed a decade ago. Since then, several ad hoc solutions to the issue have been proposed with some success in improving stability in arbitrary ways. Here, we will discuss a top-down approach which fully encompasses both full collinear kinematics and...
