We point out that Bose enhancement in a hadronic wave function generically leads to correlations between produced particles. We illustrate this general phenomenon by considering particle production within the Color Glass Condensate framework. We show that the Bose enhancement of gluons in the projectile leads to azimuthal collimation of long range rapidity correlations of the produced particles, the so-called ridge correlations.

We present a method to calculate the corrections to the eikonal approximation in the background field formalism. These corrections associated with the finite width of the target are investigated and gluon propagator in background field is calculated at next-to-next-to-eikonal accuracy. The result is then applied to the single inclusive gluon production cross section at central rapidities and the light-front helicity asymmetry, in pA collisions, in order to analyse these observables beyond the eikonal limit.

The diffractive production at small-x, including diffractive photo-production of vector mesons and dijet are powerful probes of non-linear gluon-saturation dynamics. We show that the t-distribution of photo-production of different vector mesons and dijet exhibit some universal features which offer a unique opportunity to discriminate among saturation and non-saturation models. Therefore, diffractive photo-production at the LHC and future colliders provides useful information about the underlying dynamics of particle production in the saturation regime.

We summarise the contributions to Working Group 7-Future DIS Experiments, presented during this conference. Contributions are divided into those related with the EIC projects, those related with the LHeC project, and all others.

I review the aspects of small-x dynamics that can be addressed at the proposed Large Hadronelectron Collider (LHeC) at CERN, both in lepton-proton and in lepton-nucleus collisions. After an introduction, I discuss some selected results illustrating the capabilities of such machine to provide information on structure functions, inclusive and exclusive diffraction, and other observables of interest for constraining the high-energy dynamics of QCD. I focus on inclusive observables and on the capabilities with nuclear targets.
