Alexandre Suaide is a Full Professor at the Institute of Physics of the University of São Paulo, with research activities in nuclear and high-energy physics, applied artificial intelligence, and interdisciplinary research. He conducts studies on relativistic heavy-ion collisions, investigating the formation of the quark-gluon plasma, an extreme state of matter in which quarks and gluons become deconfined, similar to the conditions that existed during the first microseconds after the Big Bang. His research focuses particularly on the production of particle jets and heavy quarks (charm and bottom) and their interaction with this plasma within the ALICE experiment at the CERN Large Hadron Collider (LHC) in Switzerland.In parallel, he develops projects in nuclear instrumentation and in the application of artificial intelligence and machine learning techniques to interdisciplinary problems. His work in this area seeks to connect methods originally developed for particle physics to applications in biology, medicine, medical image processing, and the analysis of large-scale datasets in general, promoting integration across different fields of knowledge and expanding the social and technological impact of contemporary physics research.

The involvement of São Paulo research institutions in large collaborations of high energy Physics over the past few years, largely financed by FAPESP, has brought important results for Brazilian science, as the development of the SAMPA chip, a product of high technology already used by several similar experiments around the world, and the investigation of fundamental Physics processes, su…
The focus of the School is on the most advanced technologies in the fields of semiconductors, very deep sub-micron and 3D technologies, nanotechnology, advanced packaging and interconnects, telecommunications, real-time signal processing, filtering and massively parallel computing and on the Physics motivations that require confronting these technological challenges for building the neede…
The aim of this project is to provide support for the Brazilian experimental studies of relativistic heavy ion collisions at the STAR/BNL collaboration at RHIC and the ALICE experiment at the LHC/CERN. This long-term project is receiving substantial support for over a decade and, therefore, important results have been obtained. The groups endorsing this project lead most of the activities…

The future Electron-Ion Collider (EIC) will offer unique conditions to investigate the gluonic structure of matter in high partonic density regimes, where saturation effects are expected to play a dominant role. Among the observables most sensitive to this dynamics are heavy quarks, whose production is largely governed by photon-gluon fusion and, therefore, directly connected to low-x glu…
GEM-based detectors are part of the category of micro-segmented detectors widely used in high-energy physics and nuclear physics experiments. The GEM is composed of a kapton foil coated with a copper layer on both sides and perforated using lithography techniques. Due to its geometry, it can achieve gains on the order of 10^4. The HEPIC group at the Institute of Physics at USP is developi…
Gas detectors are fundamental components present in all experiments in high energy physics. Over the past few years, investments have been made in the development of detectors with excellent spatial resolution, high signal rate counting capability and resistance to damage due to radiation. In the ALICE experiment, experiments are conducted in order to study heavy ion collisions. An upgrad…
The quark-gluon plasma is a complex structure generated in relativistic heavy-ion collisions that we treat as a tightly bound ideal fluid, but which is formed by an internal structure of loosely bound quarks and gluons. Observing this structure experimentally is an open problem, but if possible, it would allow us to understand how it gives rise to this fluid. Therefore, the purpose of thi…
In this work we propose the phenomenological study of relativistic hydrodynamics in heavy ion collisions at RHIC and LHC energies. The aim of this project consists in the study of basic theoretical aspects of relativity, fundamentals of quantum mechanics, hydrodynamics and particle physics with the goal of understanding the basic aspects of the evolution of the quark gluon plasma. Moreove…

The use of neural networks in high-energy physics has rapidly expanded, particularly in jet tagging applications. This project aims to explore leveraging convolutional neural networks (CNNs) methods to classify jets produced in high-energy collisions by differentiating between heavy quark (charm, bottom), light quark (up, down, strange) and gluon jets and background signals. The method us…
This project is a is an extension of the PhD research project which aims to study the production of heavy-flavor quarks in Pb-Pb and p-Pb collisions in ALICE (A Large Ion Collider Experiment) from CERN (European Organization for Nuclear Research) in Geneva, Switzerland. Since Pb-Pb collisions produces extreme temperature conditions, we expect the formation of a dense and hot medium, the Q…
Currently, the main goal of the high-energy nuclear physics is to understand the properties of nuclear matter at high temperatures. In ultra relativistic heavy-ion collisions experiments it is possible to create the necessary conditions for a phase transition from a cold to a hot nuclear matter. Since heavy-quarks are produced in the early stages of hadronic collisions, they are ideal pro…
Medidas de partidas com levado momento transversal propiciam o estudo dos estágios iniciais da coisão entre íons-pesados relativísticos. Em particular, medidas de distribuições angulares de píons provenientes de jatos de quarks ou glúons permitem o estudo da interação destes com o meio no qual eles se propagam. Este trabalho é um dos tópicos que se quer estudar no projeto STAR. Este proje…
