There was a bump in the middle of the night. On June 14, 2012, Johns Hopkins physics and astronomy professor Andrei Gritsan analyzed data in a small meeting room at the CERN in Switzerland. He worked ...

Scientists at CERN have discovered an ultra-rare particle decay process, opening a new path to find physics beyond our understanding of how the building blocks of matter interact. Today the NA62 ...

The NA62 Collaboration has dramatically reduced the uncertainty in its measurement of an extremely rare particle decay, in results just presented at the 2026 La Thuile conference. The study of rare ...

Six years after discovering the Higgs boson, physicists have observed how the particle decays—a monumental contribution to scientists’ understanding of the Standard Model of particle physics and the ...

Deep under a mountain in Italy, researchers continue to push the boundaries of science with an experiment that could rewrite the Standard Model of Particle Physics. Standard “double beta decay” is ...

The discovery of the muon originally confounded physicists. Today international experiments are using the previously perplexing particle to gain a new understanding of our world. At the beginning of ...

There was a huge amount of excitement when the Higgs boson was first spotted back in 2012—a discovery that bagged the Nobel Prize for Physics in 2013. The particle completed the so-called standard ...
