A generalisation of our previous approach of a renormalon-motivated resummation of the QCD observables is presented. Previously, it was constructed for those spacelike observables whose perturbation expansion is ${\cal D}(Q^2) = a(Q^2) + {\cal O}(a^2)$, where $a(Q^2) \equiv \alpha_s(Q^2)/\pi$ is the running QCD coupling. Now the resummation is generalised to spacelike quantities ${\cal D}(Q^2) = a

Ultrarelativistic heavy-ion collisions (HIC) allows us to probe the properties of strongly correlated quantum matter, at high energy density and pressure, as examined under the rationale of Quantum Chromodynamics (QCD). Even though thermalization occurs quite early in the resulting deconfined quark-gluon plasma (QGP) phase, strong transient effects depending on nearly random initial conditions pri

Exploiting the similarity between Bloch's theorem for electrons in crystalline solids and the problem of Landau gauge-fixing in Yang-Mills theory on a "replicated" lattice allows one to obtain essentially infinite-volume results from numerical simulations performed on regular-size lattices.

Heavy vector mesons provide important information about the quark gluon plasma (QGP) formed in heavy ion collisions. This happens because the fraction of quarkonium states that are produced depends on the properties of the medium. The intensity of the dissociation process in a plasma is affected by the temperature, the chemical potential and the presence of magnetic fields. These effects have been

Quark confinement is still an open and challenging problem in modern physics, with a formal explanation for its origin being pursued since the acceptance of the quark model. Advances in the area are difficult since confinement lies in the infrared regime of the theory, where perturbation theory is not applicable.

A high-pT jet with virtuality equal to its energy, dissipates energy
so intensively, that produces a leading hadron (colorless dipole) with large z promptly, on a very short time scale, which does not rise with pT.
Production of a dipole on a short time scale can be treated perturbatively.
Reasonable agreement with data at high pT is achieved.

Transcendental structures play a key role in perturbative QFT, where uniform transcendentality helps organize observables and Feynman integrals. I will discuss recent conjectures on the transcendental pattern of two-point functions of supersymmetric operators in N=4 super Yang-Mills theory and show how transcendentality guides the resummation of the perturbative series for lowest dimension operato

In this work we investigate some properties of the proton in the context of the Gauge/Gravity duality. Using holographic techniques, we study proton structure functions and its gravitational form factors. In particular, we develop a general framework that extends previous holographic calculations of $F_1$ and $F_2$ to the case where the bulk geometry stems from bottom-up Einstein-Dilaton models, w

The implementation of unitarity in high-energy hadronic scattering remains a fundamental problem in both phenomenological and theoretical analyses. We examine two distinct unitarization frameworks, the eikonal and the $U$-matrix approaches, which are employed to restore $S$-matrix unitarity in the nonperturbative regime. Although both are based on the same unitarity condition, they exhibit differe

This research project proposes to unitarize the scattering amplitude of a phenomenological model where the proton-proton interaction is mediated by the exchange of two massive Reggeized gluons. These gluons acquire a dynamical mass generated by the non-perturbative regime of QCD. The core objective is to apply a unitarization procedure to this amplitude to enable a consistent calculation of the to
