Neutrinos e a busca por física além do modelo padrão

Dr. Pedro S. Pasquini

Tsung-Dao Lee Institute & School of Physics and Astronomy, Shanghai Jiao Tong University

Abstract:

Os neutrinos foram propostos por Pauli em 1930 através de uma carta na qual ele afirma “Essa é uma ideia que eu não ouso publicar”, pois era uma partícula impensavelmente difícil de se detectar. Hoje, 90 anos depois, os neutrinos já renderam mais de 5 prêmios Nobel e tomam um papel central na física de partículas de fronteira. Mas o que uma partícula já tão estudada pode trazer de novo? Uma das poucas evidências de física além do modelo padrão: A sua massa! A massa dos neutrinos permite a existência de um fenômeno chamado de oscilação de neutrinos, onde neutrinos de um tipo se transformam em outro. O estado da arte de experimentos de neutrinos buscam medir os parâmetros que controlam as oscilações. Estes podem trazer evidências de física nova em escalas de energias que não são alcançadas por grandes aceleradores.

Sirius, o novo síncrotron brasileiro, imagem por raios X e aplicações em fluxo de fluidos em meios porosos para remediação de aquíferos e extração de petróleo

Dra. Nathaly Lopes Archilha

Laboratório Nacional de Luz Síncroton (CNPEM)

Abstract:

Sirius, a nova fonte de luz síncrotron brasileira, é uma instalação aberta que está à disposição da comunidade científica brasileira e internacional, e faz parte do CNPEM, o Centro Nacional de Pesquisa em Energia e Materiais, situado em Campinas, SP. As linhas de luz do Sirius foram projetadas para abrigar instrumentação científica super avançadas, que são capazes de solucionar questões importantes em áreas estratégicas para o desenvolvimento do Brasil. O Sirius pode abrigar até 38 linhas de luz e 14 delas já estão sendo executadas, algumas já estão operacionais e recebendo pesquisadores. Diversas dessas linhas são dedicadas à produção de imagem (2D, 3D, 4D, etc…), e a Mogno, linha coordenada pela palestrante, é capaz de produzir imagens com alta resolução temporal (uma imagem 3D em um segundo) e espacial (entre 100 nm e 55 mm), possibilitando a realização de medidas resolvidas no tempo, mais conhecida como tomografia 4D. Essa técnica permite o estudo de variação estrutural de amostras quando submetidas à pressão, temperatura, tensão, vazão de fluidos, etc. Nesse seminário, serão apresentadas oportunidades de cursos, treinamentos e participação de workshops organizados pelo CNPEM, além de exemplos de experimentos realizados em uma linha de imagem, relacionados à recuperação avançada de petróleo e à remediação de águas subterrâneas.

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.
