A sub-atomic particle predicted to exist by physicists has been detected for the first time in a particle accelerator in California – but its properties do not fit with theory. The particle, called Ds ...

The Department of Energy’s Fermi National Accelerator Laboratory near Chicago. If accurate, it’s a sign that the theories forming the foundation of modern particle physics don’t tell the whole story.

The goal of nuclear physics is to describe all matter from its simplest building blocks: quarks and gluons. Found deep inside protons and neutrons, quarks and gluons also combine in less common ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

In physical sciences, subatomic particles can be composite particles, such as the neutron and proton, or elementary particles. Based on the standard model, elementary particles are not made of other ...

When it was time for the 2013 Nobel prize in physics to be announced, Peter Higgs went fishing. Andy Rain/EPA Images Peter Higgs, who gave his name to the subatomic particle known as the Higgs boson, ...
