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 ...

The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays ...

Recent findings from research we have been carrying out at the Large Hadron Collider (LHC) at Cern in Geneva suggest that we might be closing in on signs of undiscovered physics. If confirmed, these ...

The future circular collider at CERN, intended to probe the properties of the Higgs boson in 20 years' time, excites ...

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 ...

For over two decades, scientists at CERN observed unexplained particle losses in their Super Proton Synchrotron. A new study ...

As foretold, the Relativistic Heavy Ion Collider—among the most powerful heavy-ion colliders in the world, second only to CERN’s LHC—ran its final particles and ceased operations last Friday. This is ...

When trying to answer questions as deep as “what makes up the universe,” advance planning is key. On June 11, the National Academies of Science, Engineering and Medicine announced the result of a ...
