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 ...

Eight decades after one of the weirdest discoveries in the history of science -- that subatomic matter is wavelike -- Austrian scientists are studying the same phenomenon on a much bigger scale, in ...

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 ...

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, ...

The United States' military has announced it is seeking to create powerful subatomic particle beams that would enable personnel to "see" through walls tens of yards thick and even peer deep ...

The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions ...

Scientists have made an unprecedented close examination of the electron, providing fascinating new insights into the nature of particles, energy and forces at infinitesimally small scales. A ...

To peer into the heart of the sun, a 13.7-meter-wide stainless steel shell lined with over 2,200 light-gathering sensors hides deep under a mountain in central Italy. Known as the Borexino experiment, ...

A shower of subatomic particles has revealed the outlines of an empty cavity inside the Great Pyramid at Giza in Egypt — the first discovery of a new internal structure in almost two centuries.

The pentaquark, a particle that eluded physicists for decades before finally being discovered in 2015, is starting to give up its secrets. New data from the Large Hadron Collider (LHC) in Switzerland ...

Feynman diagrams are a powerful tool in condensed matter physics. By turning highly complex equations into sets of simple diagrams, the method has established itself as one of the sharpest tools in a ...
