The Balitsky–Kovchegov (BK) equation offers a tractable description of the high‑energy growth of gauge‑theory scattering amplitudes and the nonlinear saturation effects that eventually tame this growth. Motivated by the upcoming precision era at the Electron–Ion Collider (EIC)—whose extended kinematic reach promises decisive tests of saturation—we present a framework based on the...

The search of the signatures of saturation is one of the main goals of the future Electron-Ion Collider (EIC). In this regime the background field of the target is characterized by the shock-wave structure defined by the eikonal interactions. However, we expect that this limit will be hard to achieve at EIC, due to the moderate values of the scattering energies. Instead, the leading eikonal...

We calculate the elastic production of dijets from electron collisions with a longitudinally polarized proton target at small values of the Bjorken $x$ variable. Building on the pioneering proposals of Hatta et al and Bhattacharya et al for measuring the quark and gluon orbital angular momentum (OAM) distributions, our focus is on both the longitudinal double spin asymmetry (DSA) and...

Dihadron angular correlations in forward pA collisions provide a sensitive probe of gluon saturation effects. In these processes, both gluon saturation and parton shower dynamics contribute to the observed de-correlation between back-to-back dihadron pairs. In our study, we employ the Color Glass Condensate (CGC) framework to perform a detailed numerical investigation of dihadron correlations...

Energy-energy correlators (EEC) are event-shape observables that have gained renewed interest in the recent years, due to them being less sensitive to the non-perturbative hadronization of the final-state particles. In this talk, I will discuss the EEC in $pp$ and $pA$ collisions in the collinear limit where the studied particles are inside the same jet. This type of EEC allows us to probe jet...

The jet energy-energy correlator (EEC), which measures angular correlations of energy flow inside jets, provides a sensitive probe of jet substructure and its modification by the nuclear medium. We compute the EEC for jets produced in electron-proton and electron-nucleus deep inelastic scattering, focusing on medium-induced corrections arising from final-state interactions in cold nuclear...

We investigate transverse energy-energy correlators (TEECs) for both polarized and unpolarized targets in the small-x regime at the Electron-Ion Collider (EIC). Focusing on the approximately back-to-back electroproduction of a hadron-electron pair, we apply transverse-momentum-dependent (TMD) factorization formulas that incorporate TMD evolution for both event-shape observables and expand them...

The Color Glass Condensate (CGC) is an effective field theory that describes the behavior of hadrons and nuclei at high energies (corresponding to small values of Bjorken-x), where the rapid growth of gluon densities is expected to be moderated by saturation effects. In this talk I will show that within the CGC dilute-dense formalism, the cross section for dijet production involving a small-x...

We study the small-$x$ asymptotics of unpolarized generalized parton distributions (GPDs). Unlike the previous works in the literature, we consider the case of non-zero skewness. We show that the unpolarized GPDs at small $x$ are related to the eikonal dipole amplitude $N$, whose small-$x$ evolution is given by the BK/JIMWLK evolution equations. We show that the effect of non-zero skewness...
