Why it matters: Physicists at the University of Manchester report evidence for a decay expected in only around one of every 10 billion beauty particles.

The University of Manchester said its physicists have found evidence of a particle decay of extreme rarity.

According to the university, the decay is expected to happen only about once in every 10 billion so-called beauty particles.

The university described the finding as the result of a particle search lasting 42 years and as a step closer to what it calls the ‘Zeptoverse’.
