CERN Set to Further Limit Collaborations with Russia-Affiliated Scientists

The European Organization for Nuclear Research (CERN), known for its stewardship of the world's largest and most powerful particle accelerator, the Large Hadron Collider, is reportedly taking definitive steps to sever scientific ties with researchers linked to Russian institutions. An anonymous CERN-affiliated physicist brought this development to light, with another participant from a current project confirming the clampdown on collaborations, despite any ongoing contracts.

This move effectively shuts down a critical pathway for Russian scientists and those of other nationalities engaged at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, who sought to partake in CERN-led inquiries. Especially for those who haven't previously been involved in CERN projects, the door will soon be irrevocably closed.

Marked to commence on December 1, 2024, the initiative underscores a broader disengagement effort where new cooperations with Russian-located entities, such as JINR, will be curtailed, reflecting an intensified scrutiny of partnerships amidst growing geopolitical tensions. Such restrictions, although multinational in scope, will disproportionately impact Russian science by preventing not only existing but also budding researchers from accessing vital international facilities and expertise.

This staunch policy poses significant roadblocks for scientists worldwide, casting a shadow over the collective pursuit of scientific advancement. Researchers rooted in Russian academia find themselves at a particularly stark crossroads, facing the potential erasure of profound investments in time, expertise, and significant advancements within the experimental high-energy physics realm. The impending departure of established Russian teams from CERN's fold will likely leave discernible gaps in the institution’s research domain.

Furthermore, the insider conversations indicate a nuanced rationale behind this severance, connected to the broader international response against Russia's political actions. Despite the productive relationship historically shared between CERN and Russian science institutions, CERN is consciously opting to distance its inherent cosmopolitan scientific culture from entities endorsing Russia's current political stances through their leadership.

Although the official CERN releases have not yet addressed this specific decree, the internal decision, which hitherto is said to have been "communicated verbally to the staff," foreshadows a seismic shift in international scientific collaboration. By disallowing the influx of new talent—irrespective of their nationality—if they carry affiliations with Russian institutions, CERN is casting a non-negotiable verdict on the future of entire scientific schools and the upward trajectory of potentially transformative high-energy physics research.
