TL;DR
This work assesses Brazil's contribution to the ESPP Update by outlining current participation in LHC experiments, detector and accelerator R&D, and non-collider projects, in the context of Brazil's 2024 Associate Member State status at CERN. It argues that the Future Circular Collider (FCC) proposal, including FCC-ee and FCC-hh, best aligns with Brazil's technical strengths and industrial partnerships, while recognizing LCF@CERN as a viable fallback. The analysis considers timelines, funding, and currency risks, proposing a phased plan for R&D, construction, and commissioning to mitigate human-resource constraints. The study aims to guide Brazil's national strategy toward sustained CERN collaboration, technology transfer, and socio-economic benefits through green computing and industrial spillovers.
Abstract
The Brazilian High-Energy Physics (HEP) community has expanded remarkably since its first involvement at CERN and Fermilab in the 1980s. Its recent organization under the Brazilian Network for High-Energy Physics (RENAFAE), since 2008, has further strengthened its scientific and technological goals, particularly in detector instrumentation, computing, and industry partnerships. In 2024, Brazil became an Associate Member State of CERN, opening new opportunities for deeper engagement in accelerator and detector R&D. This input to the 2026 update of the European Strategy for Particle Physics highlights Brazil's current participation in LHC experiments as well as ongoing developments in detector and accelerator technology, and details the community's view towards future colliders. The potential for expanded scientific and industrial collaborations between Brazil and CERN is also discussed.
