We may already have had our first-ever encounter with dark matter, according to researchers who say a mysteriously ...

Some quick background: Both quarks and photons are ... So the scientists wanted to make photons collide with a composite particle like a proton to learn about how particles function.

Studying a new, very heavy particle helps us view underlying physical processes – often without annoying background noise ... the Higgs boson is in fact a composite object made of other particles.

Researchers from Tokyo Metropolitan University have used computer simulations to model how a composite material reacts to loading. They studied a particle model of a pillar of stiffer material in ...

July 2012 was a watershed moment for particle physics, as enough high-energy collisions were reconstructed to definitively announce, in both detectors, the first concrete, direct evidence for the ...

While they normally have a mass and an electric charge, Pines asserted that they can combine to form a composite particle that is massless, neutral, and does not interact with light. He called ...
