I review the derivation of TMD factorization theorem and the main properties of TMD distributions
I will review the origins and the formalism of quantum spectral curve
(QSC) computing the anomalous dimensions of operators at any coupling in
maximally sypersymmetric (N=4) Yang-Mills theory in the planar limit.
Then I will demonstrate how to extract from QSC the Regge limit (small
coupling, spin close to -1) for the dimension of twist-2 operator and to
reproduce the LO BFKL formula.
We will review some aspects of collinear resummations in the BFKL formalism, showing some phenomenological applications and more recent developments from the formal side.
After a brief introduction on the peculiarities of QCD in the high-energy regime and the bFKL approach for its description, we proceed to the theoretical
analysis of virtual photon scattering.
Here, the crucial theoretical objects are the photon impact factors and the BFKL gluon Green's function, which up to now are known in leading and
next-to-leading logarithmic approximation.
We...
In this talk, I will present a recent computation of the back-to-back dijet cross-section in deep inelastic scattering (DIS) at small $x$ to next-to-leading order (NLO) in the Color Glass Condensate effective field theory [1]. I will show that the result can be factorized into a convolution of the Weizsäcker-Williams gluon transverse momentum dependent distribution function (WW gluon TMD) with...
In 2308.02449, I have performed the NLO calculation for forward virtual photon plus jet production in the hybrid dilute-dense Color Glass Condensate framework. I give an outline how this calculation can be extended to compute the inclusive forward Drell-Yan cross section at low transverse momentum.

We compute the Next to Leading Order corrections to single and double inclusive hadron production in DIS at small x. We show that rapidity divergences can be absorbed in to Leading Log evolution of dipoles and quadrupoles that describe the target.
The talk will cover recent results for one-loop impact-factors involving quarkonium states, obtained using Lipatov's Gauge-Invariant EFT for Multi-Regge processes in QCD.
We study the single-inclusive particle production from proton-nucleus collisions in the dilute-dense framework of the color glass condensate (CGC) at next-to-leading order (NLO) accuracy. In this regime, the cross section factorizes into hard impact factors and dipole-target scattering amplitude describing the eikonal interaction of the partons in the target color field. For the first time, we...
I discuss different types of power corrections in the TMD factorization, their theoretical and practical aspects. I provide overview of the current status and perspectives in this field. The special emphasis is done on the kinematic power corrections and their importance to reach the consistent factorization formula.
