Scientists Find Evidence of Rarest Particle Decay After 42-Years
Physicists at CERN's Large Hadron Collider have found evidence of an extremely rare particle decay known as 'Bd to mu mu' after 42 years of research. This discovery helps scientists better understand fundamental physics and the nature of dark matter.
Why it matters
Confirming rare particle behaviors provides critical data for testing the Standard Model of physics and exploring the 'Zeptoverse'.

The discovery, supported by the Science and Technology Facilities Council (STFC), provides evidence for the rarest decay of a 'beauty' particle ever seen at the LHC.
The result brings physicists closer to exploring the 'Zeptoverse', a world of extremely small distances, around a billionth of a trillionth of a meter.
Here new particles and fundamental forces of nature may be hiding.
