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 ...

Quantum chromodynamics, or QCD, is the theory of the strong interaction between quarks and gluons. Lattice QCD uses supercomputers to explore 'tantalizing hints' of new physics in discrepancies ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

Electrons are still almost perfectly round, a new measurement shows. A more squished shape could hint at the presence of never-before-seen subatomic particles, so the result stymies the search for new ...

Predicting the properties of subatomic particles before their experimental discovery has been a big challenge for physicists. In a recent paper published on 28 July in Physical Review Letters Nilmani ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

A new study suggests that many theorized heavy particles, if they exist at all, do not have the properties needed to explain the predominance of matter over antimatter in the universe. If confirmed, ...
