Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped inside a nucleus. This exotic state may reveal how mass is generated, ...

Scientists working at CERN’s Large Hadron Collider may be seeing the strongest hints yet of physics beyond the Standard Model — the decades-old theory that explains the fundamental particles and ...

A team of theoretical physicists has proposed a new particle existing in a warped fifth dimension that could bridge ordinary matter with dark matter. The model, published in The European Physical ...

Physicists know that their elegant theoretical description of forces and particles — the standard model of particle physics — must be incomplete, because there are a host of phenomena it cannot ...

Anyone who has been paying attention to cosmology over the past few years is aware of problems with our best attempts to explain why the universe is the way it is. Our standard model, Lambda-CDM (or ...
