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.

Dimuon production in neutrino-nucleus collisions remains an important constraint of strangeness in nucleons. In most global analyses of proton and nuclear parton distribution functions, dimuon production is computed by assuming factorization to inclusive charm DIS production, an assumption that is valid only at leading order in the fixed-flavor number scheme. Our approach based on...

Fragmentation functions describe the formation of final-state hadrons from high-energetic partons. As they are non-perturbative objects they cannot be calculated from first principles in QCD but need to be measured. Especially e+e- annihilation is a clean tool to extract fragmentation functions since no hadrons exist in the initial state.

The deuteron has a unique feature called tensor polarization, which cannot be obtained by simply combining of the proton and neutron properties and provides access to new tensor structure functions that reflect genuine nuclear effects arising from QCD dynamics, showing how quarks and gluons are modified by binding and spin correlations in a spin-1 nucleus. These functions provide a...

We study the Drell-Yan structure functions in $Z^0$ boson production within the $k_T$ factorization framework, with particular emphasis on the Lam-Tung relation. The NNLO predictions in collinear perturbative QCD underestimate the ATLAS measurement of the Lam-Tung structure function. We investigate impact of parton transverse momenta on description of this observable and the other Drell-Yan...

The Standard Model (SM) of particle physics describes the fundamental particles and their interactions with remarkable precision. Yet, it cannot explain key mysteries such as the nature of dark matter, the role of gravity, or why the universe contains more matter than antimatter.
With no new particles directly observed at the Large Hadron Collider (LHC), the most promising approach is to...

Deep-inelastic scattering at small Bjorken-$x$ is best studied in the dipole model, where the virtual photon emitted by the lepton projectile fluctuates into a quark--antiquark pair that propagates through the dense hadronic target. In this framework, the cross section is given as a convolution of an impact factor and target matrix elements of Wilson lines along nearly lightlike trajectories....

Complete N3LO predictions require knowledge of the splitting functions at four loops. In this talk, I discuss our calculation of the four-loop non-singlet splitting functions from off-shell operator matrix elements. We obtain complete results with exact x-dependence for all non-singlet splitting functions and extract the virtual and rapidity anomalous dimensions in analytical form.
