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 ...

STARKVILLE, Miss.—A Mississippi State physicist and her colleagues are the first scientists to observe how subatomic particles—known as lambda particles—are formed, helping researchers learn more ...

At its start, the universe was a superhot melting pot that very briefly served up a particle soup resembling a "perfect," frictionless fluid. Scientists have recreated this "soup," known as ...

Until now, observing subatomic structures was beyond the resolution capabilities of direct imaging methods, and this seemed unlikely to change. Czech scientists, however, have presented a method with ...

More than three years after discovering a never-before-seen subatomic particle, physicists now know how these particles — called pentaquarks — are put together. New research reveals three completely ...

Manhattan-born physicist Murray Gell-Mann, who revolutionized the discovery and classification of subatomic particles, died Friday at the age of 89. Famous for detecting a slew of theoretical specks, ...

The Large Hadron Collider in Geneva is getting bigger. The giant particle accelerator—sometimes referred to as an atom smasher—causes collisions between beams of high-energy particles to study their ...
