Oral Presentation
We present a new method to systematically calculate corrections to the eikonal approximation in the background field formalism. We calculate the subleading power-suppressed corrections due to the finite width of the target to first and second orders. The method is of generic applicability. As a first example, we study both polarized and unpolarized gluon production in pA collisions.

This talk discusses the derivation of the NLO evolution equations for the quadrupole and the double dipole operators. It contains the evolution equations for both the standard and the conformal composite operators.

Oral Presentation
The distribution of quarks and gluons produced in the initial stages of nuclear collisions, known as the initial condition for the Quark-Gluon Plasma formation,
is the fundamental building block of heavy ion theory.
I will present the scattering amplitude, beyond the leading order, of the classical gluon produced in heavy ion collisions. The result is obtained in the framework of saturation...

Oral Presentation
The searching of saturation effects in inclusive and exclusive $eA$ collisions is reviewed. In particular, we present a comparison between the linear and nonlinear predictions for the nuclear structure functions as well as for the vector meson production in future $eA$ colliders. Finally, we present our recent results for the nuclear Deep Virtual Compton Scattering.

We study the Feynman $x_F$ distribution of leading neutrons produced in $e + p \rightarrow e + n + X$ reactions. Using the factorization
approach, we write the differential cross section in terms of the pion flux and the pion - photon total cross section. The latter is related
to the dipole scattering amplitude, which contains information about the QCD nonlinear effects and gluon...

Oral Presentation
I will discuss in details whether there is a ridge like structure in di-photon correlations in high-multiplicity events in p+p and p+A collisions at the LHC. Such measurements at the LHC and future colliders provides useful complementary information about the underlying dynamics of particle production in high-multiplicity events, and help to understand the true nature of the observed ridge...

We determine the distribution of linearly polarized gluons of a dense target at small $x$ by solving the JIMWLK rapidity evolution equations. From these solutions we estimate $\sim \cos 2\phi$ azimuthal asymmetries in DIS dijet production at high energies. We find sizeable long-range in rapidity azimuthal
asymmetries with a magnitude in the range of $v_2=\langle\cos2\phi\rangle\sim 10\%$.

We use the running coupling Balitsky–Kovchegov (rcBK) equation to study
the rapidity dependence of saturation in inclusive HERA data and we discuss
the behaviour of it’s numerical solution. The rcBK equation has been solved
using Runge–Kutta methods. The influence of the parameters implicit in
the numerical evolution has been studied. They include, among others, the
order of the...
