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 ...

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 ...

Muons are one of the key subatomic particles for discovering new physics, but tracking them after particle collisions can be difficult and prone to error. A new study ...

Researchers can use the Standard Model of Particle Physics to make very accurate predictions about how subatomic particles interact and decay. However, there are gaps in the Standard Model that ...
