Scientists Detect Signals From the Zeptoverse at CERN

Scientists have detected previously unexplored particle interactions at an extraordinarily small scale, potentially opening new avenues for investigating dark matter. The discovery, announced on November 3, 2026, emerged from research led by Cambridge-based scientists using the Large Hadron Collider (LHC) at CERN on the Swiss-French border.

The signals originated from interactions occurring at a scale of a billion-trillionth of a meter, approximately 100 billion times smaller than an atom. Some physicists have nicknamed this newly explored territory the zeptoverse.

The experiment involved accelerating particles to high energies and colliding them to examine the resulting debris. Researchers focused on beauty quarks, unstable subatomic particles that exist for approximately one and a half trillionths of a second before decaying into other particles.

Scientists believe these interactions could provide clues about dark matter, an invisible substance whose existence is inferred from its gravitational influence on ordinary matter. Some theoretical models suggest dark matter could affect particle interactions at extremely small scales.

Dr Harry Cliff of Cambridge University, who led the analysis, described the discovery as an initial step toward investigating this previously inaccessible territory.

"We're knocking on the door of this zeptoverse," said Dr Harry Cliff.

He explained that the observed interactions offer researchers an opportunity to investigate the behavior of potentially undiscovered particles.

"And what we want to do now is go in and explore and find what new particles are waiting there. And to do that, what we need is more data," said Dr Harry Cliff.

A planned upgrade to the LHCb detector is expected to increase the frequency of these particle decays tenfold. According to the research team, 28 countries involved in the project have agreed to contribute £150 million toward the improvement.

"With that we can probe inside the zeptoverse and see what's waiting," said Dr Harry Cliff.

However, the United Kingdom's participation has become uncertain following funding reductions. UK Research and Innovation (UKRI), the government agency responsible for research funding, previously withdrew its contribution to the proposed detector upgrade.

Prof Tim Gershon, leader of the international LHCb collaboration, warned that the decision could undermine British involvement in future discoveries.

"The UK is at risk of not being involved and making really major discoveries," said Prof Tim Gershon.

He also highlighted the potential consequences for scientific education and opportunities for emerging researchers.

"But I think the biggest long-term impact comes from the fact that the UK won't get the benefits from training young people who really are our greatest product," said Prof Tim Gershon.

The funding reductions have also affected several other particle physics and astronomy projects, including the Lovell Telescope at Jodrell Bank.

Dr Mary Richardson-Slipper, an early-career researcher involved in the discovery, said the situation had prompted her to reconsider her professional future in Britain.

"I love being here in the UK, but I am looking at jobs abroad because that seems to be where there are more opportunities at the moment," said Dr Mary Richardson-Slipper.

She indicated that many other researchers working in fundamental physics had already relocated abroad.

Prof Brian Cox, a University of Manchester particle researcher and television presenter who was not involved in the study, described the discovery as important and criticized the funding decision.

"It would be extraordinary to walk away from UK scientific leadership at this moment, damaging the future research programme and seriously damaging our hard-won international reputation," said Prof Brian Cox.

UKRI defended its funding strategy, emphasizing that Britain remains CERN's second-largest financial contributor, providing approximately £175 million annually.

A UKRI spokesperson said the agency had consulted independent advisers before selecting its research infrastructure investments.

"We sought independent advice and have taken forward an exciting portfolio of new infrastructure investments, which include projects in clean energy, medical imaging and cultural heritage," said a UKRI spokesperson.

The agency acknowledged that some research proposals could not receive financial support because available funding was limited.

"However, as usual, there were more exciting applications for funding than we were able to support," said a UKRI spokesperson.
