The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Thanks to the laws of physics, the atoms that make up everything that exists don’t go randomly flying apart all day long. Thanks to a new discovery by those particle-smashing scientists at CERN, we ...

The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

Here’s what you’ll learn when you read this story: Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing ...

A signal from the decay products of a meson—a quark and an antiquark—comes from two subatomic particles and not one, as previously thought. High-energy collision experiments have helped particle ...

Protons are particles that exist in the nucleus of all atoms, with their number defining the elements themselves. Protons, however, are not fundamental particles. Rather, they are composite particles ...
