Why matter dominates over antimatter in our universe has long been a major cosmic mystery to physicists. A new finding by the world's largest particle collider has revealed a clue.

Physicists have set a new upper limit on the mass of neutrinos. And the finding could poke a big hole in the Standard Model of particle physics.

Physicists are finalizing plans for MATHUSLA, a powerful new addition to CERN's Large Hadron Collider that will detect long-lived particles and potentially open the door to new physics.

Physicists have long-suspected that the building blocks of protons experienced quantum entanglement. Now, researchers have the first direct evidence — after using a trick to infer subatomic particles' entropy.

There's a significant imbalance between matter and antimatter in our universe, but a strange particle called "the Majoron" could finally explain it, an audacious new study suggests.

A new underground facility called DUNE, which will accelerate particles for 800 miles between Illinois and South Dakota, could reveal the hidden dimensions of the universe, new research suggests.

Scientists at CERN's ALICE detector are replicating conditions found during the Big Bang, attempting to get to the bottom of how matter came to dominate over antimatter.

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to get there.

Primordial black holes may be exploding throughout the universe. If we can catch them in the act, it could pave the way to new physics, a study suggests.

The discovery of two entangled quarks at the large Hadron Collider is the highest-energy observation of entanglement ever made.
