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 ...

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 ...

Subatomic particles, gravity wells and the beginning of the universe – these are difficult and mysterious concepts that are better understood with storytelling and metaphor. That's exactly theoretical ...

China is nearing completion of an advanced facility to measure neutrinos, the smallest subatomic particles known to physicists. Its underground central sphere will soon be sealed off and filled with ...
