High-energy QCD dynamics with sub-eikonal corrections
Giovanni Antonio Chirilli
University Of Regensburg
Abstract:
At very high energies, when parton density in hadronic target becomes very high, the cross section reaches the unitarity (saturation) limit. At this regime the QCD dynamics is described by the non-linear BK and JIMWLK evolution equations within the eikonal approximation and infinite Wilson-line operators. These equations are currently the starting point of discussion for future experiments like the Electron Ion Collider (EIC) or the Large Hadron electron Collider (LHeC) and play an important role in current RHIC and LHC experiments involving nucleus-nucleus and proton-nucleus collisions. However, many interesting aspects of hadron dynamics are not accessible within the eikonal approximation, the spin physics being an obvious example. The higher precision reached by the experiments and the possibility to probe spin dynamics at future Electron Ion Colliders make the study of deviations from eikonal approximation especially timely. I will review the high-energy Operator Product Expansion and Wilson line formalism as well as the derivation of the non-linear evolution equations up to next-to-eikonal accuracy.

Visiting professor at the Graduate Program in Physics at UFSC and particle physics researcher at Lund University
The professor Roman Pasechnik, visiting professor at the Graduate Program in Physics at UFSC and particle physics researcher at Lund University, he is part of the Swedish-Hungarian research group that discovered the mythical particle Odderon with the help of an extensive analysis of experimental data from the Great Collider of CERN hadrons in Switzerland. For 50 years, the research community has been unsuccessfully searching for this particle.
More details about the discovery can be accessed in physics.org.

Efeitos pré-hidrodinâmicos em colisões ultra-relativísticas de íons pesados
Prof. Dr. Tiago José Nunes da Silva
Departamento de Física | UFSC
Abstract:
Plasma de quarks e glúons (QGP) é um estado extremo da matéria fortemente interagente constituído por uma “sopa” de quarks e glúons não-confinados. As condições extremas necessárias para sua formação podem ser naturalmente encontradas no universo primordial e, especula-se, no interior de objetos astrofísicos ultra-compactos, como as estrelas de nêutrons. Podem, também, ser recriadas em experimentos de colisões ultra-relativísticas de íons pesados, que têm sido conduzidos, por exemplo, no LHC e no RHIC.
Nesse seminário, veremos como investigar os diversos processos físicos que acontecem durante tais experimentos utilizando um modelo numérico híbrido para simular todas as diferentes etapas de uma colisão de íons pesados, incluindo a evolução do QGP através da hidrodinâmica relativística viscosa. Em seguida, abordaremos como diferentes cenários para a descrição da etapa pré-hidrodinâmica podem impactar os observáveis experimentais do estado final e apontaremos possíveis caminhos para o refinamento dos modelos em questão.

“Bragg and Debye were right !”
Norberto Masciocchi
University of Insubria and To.Sca.Lab, Italy
Abstract:
This presentation will cover more than 100 years of structural methods for crystalline matter, emphasizing the key steps which made it possible to define stable and efficient protocols for deriving otherwise inaccessible structural information at the atomic resolution. 20th century crystallographers paved the way to the obtention of structure, microstructure, morphology, and defectiveness of many functional materials, by devising theories and experiments which, in 2021, have been further optimized to an unprecedented level. Examples from the sagacious use of polycrystalline diffraction/scattering techniques for real materials, assisted by unmatched computational power, will be provided, and the complementarity of Bragg’s and Debye approaches will be highlighted.
