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 ...

Scientists at CERN, the home of the Large Hadron Collider, have just observed an astoundingly rare phenomenon at the subatomic level that could lead to a new understanding of the standard model of ...

When protons smash against a beryllium target in CERN’s Super Proton Synchrotron (SPS), the resulting subatomic chaos produces a smattering of kaons—a kind of subatomic particle. Physicists predict ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

The Belle II experiment has recently made precise measurements of the lifetime of subatomic particles called quarks and leptons (such as electrons and neutrinos). These particles are believed to be ...
