Scientists Detect Signals From the Zeptoverse
Researchers at CERN's LHCb experiment picked up a rare particle process at a scale about 100 billion times smaller than an atom.
Updated on Nov. 3, 2026 in Physics
Scientists detected evidence of an extremely rare subatomic process at the Large Hadron Collider's LHCb experiment at CERN. The signals come from a scale physicists have nicknamed the 'zeptoverse'.
Why it matters
The finding opens a window into physics at scales far smaller than atoms, where new particles may exist. Researchers say more data will be needed before any new particles can be identified at this scale.
The analysis examined a process involving a particle containing a beauty quark that breaks down into two muons, at a scale of about one zeptometre. Further data is needed before any conclusions about new particles can be drawn.

A University of Cambridge physicist who led the analysis of the LHCb data.
CERN
The European Organization for Nuclear Research, the particle physics laboratory on the Swiss-French border that operates the Large Hadron Collider.
The details
Physicists at the University of Cambridge, led by Dr Harry Cliff, analyzed data from the LHCb experiment at CERN, the European particle physics laboratory on the Swiss-French border. The Large Hadron Collider smashes particles together at high speeds, and scientists study the smaller particles these collisions produce.
Timeline
Research results were reported in November 2026.
The Big Picture
The LHCb experiment is designed to probe rare decays of beauty quarks that could reveal physics beyond the Standard Model. This zeptoverse signal extends that search into a scale far smaller than atoms.
Discoveries at this scale are foundational research and are not expected to produce consumer products soon. Their practical value lies in testing the theories that underpin future technologies.
The takeaway
Even the smallest scales of matter still hold unanswered questions, and each rare signal helps physicists refine what they know about the universe's building blocks.
