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 ...

Physicists know that their elegant theoretical description of forces and particles — the standard model of particle physics — ...

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 ...

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same uncomfortable conclusion: something is producing signals that the Standard Model of ...

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 ...
