A surprising and rare particle decay has left scientists puzzled as kaons, particles made up of quarks, are decaying in ways that defy current physics models. Could this anomaly indicate the existence ...

Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing investigation of CP symmetry. The anomalies could be ...

In a particle collider at CERN, a rarely-seen event is bringing us tantalizingly close to the brink of new physics. From years of running what is known as the NA62 experiment, particle physicist ...

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 ...

Scientists at the South Dakota School of Mines and Technology have produced two distinct sets of neutrino-related results ...

UPTON, NY — After careful study of six trillion subatomic particle decays, an international collaboration of physicists announced that they have spotted one of the rarest occurrences in the subatomic ...

Scientists have proposed a new kind of subatomic particle to explain another particle’s mysterious disintegration. The kaon, a special case of meson particle, is made of one quark and one antiquark.
