Effective April 2, 2026, Chile became an Associate Member State of CERN, the European Organization for Nuclear Research. The status entered into force following Chile’s ratification of the Associate Member State Agreement of May 2025 and its accession to the Protocol on CERN’s Privileges and Immunities.
According to CERN, Chile is “entitled to be represented at the CERN Council, Finance Committee and Scientific Policy Committee.” Chilean nationals may now apply for CERN staff positions and graduate programs, and Chilean firms are eligible to bid on CERN procurement contracts.
CERN’s partnership with Chile dates to 1991. Chilean institutions currently participate in the ATLAS, CMS, and LHCb experiments, as well as the SND@LHC, NA64, and SHiP collaborations and the ISOLDE facility. CERN stated that Chile’s new status “marks a significant deepening of CERN’s relations in the Americas.”
