Keeping high-power particle accelerators at peak performance requires advanced and precise control systems. For example, the primary research machine at the U.S. Department of Energy's Thomas ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

Something odd is happening deep inside the data streams from CERN’s Large Hadron Collider. A set of “forbidden” patterns in how unstable particles decay, combined with rare Higgs events and a ...

AI is searching particle colliders for the unexpected ...

Physicists have shown that particles produced in collimated sprays called jets retain information about their origins in subatomic particle smashups. Physicists at the U.S. Department of Energy's (DOE ...

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an experiment.

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.
