Brazil is represented in IPPOG by the National Network of High Energy Physics (Rede Nacional de Física de Altas Energias, RENAFAE, in Portuguese), officially created by the Brazilian Ministry of Science and Technology to coordinate the national effort in High Energy Physics. The country has a long tradition in High Energy Physics and its outreach. The event Masterclasses Hands On Particle Physics is applied in the country since 2008 and nowadays more than a 1000 students are reached every year in different institutions spread around the country. By the time Brazil was joining IPPOG, a Working Group was created congregating Particle Physicists and Science Education Experts from different Brazilian institutions around the country to promote particle physics outreach activities and to represent the country in IPPOG. Several initiatives are been developed by this group as the organization of regular meetings to exchange ideas and start new collaborations among the participants. For instance, a project to introduce cosmic ray detectors in elementary schools was born from this group. Given the size and demands of the country, uncountable initiatives and activities can still be created to promote particle physics and scientific knowledge in Brazil.

The Swedish particle physics research activities are centered at universities, with groups working on e.g. the ALICE, ATLAS, and LDMX experiments, as well as astroparticle experiments like XENON, IceCube, Hyper-Kamiokande, as well as substantial activities in theory and phenomenology research. Many groups are very involved in outreach activities with PhD students, postdocs, and faculty members organizing events at museums, giving guided tours at CERN, Masterclasses for high school students, etc. Our goals is to communicate why particle physics research is important, how it is done, and what benefit it brings to society on both the shorter and the longer time scales.

ALICE is a heavy-ion experiment, designed to study the collisions of nuclei at the ultra-relativistic energies provided by the LHC. The aim is to study the physics of strongly interacting matter at the highest energy densities reached so far in the laboratory. In such conditions, an extreme phase of matter - called the quark-gluon plasma - is formed. Our universe is thought to have been in such a primordial state for the first few millionths of a second after the Big Bang, before quarks and gluons were bound together to form protons and neutrons. Recreating this primordial state of matter in the laboratory and understanding how it evolves will allow us to shed light on questions about how matter is organized and the mechanisms that confine quarks and gluons.
