For decades, physicists searched for a missing piece of nature's puzzle, an elusive particle believed to explain why matter ...

Europe's physics lab CERN is planning to build a particle-smasher even bigger than its Large Hadron Collider to continue searching for answers to some of the universe's tiniest yet most profound ...

His work paved the way for the discovery of the Higgs boson, which explained how particles acquire mass, solving one of the ...

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 standard model (SM) of particle physics is the mathematical description of the fundamental constituents and interactions of matter. Its last missing particle, the Higgs boson, was observed in 2012 ...

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.

Despite its tremendous success in predicting the existence of new particles and forces, the standard model of particle physics, designed over 50 years ago to explain the smallest building blocks of ...
