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.

To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of ...

Scientists have inched a step closer to solving an enduring mystery in physics — why the universe contains any matter at all — thanks to a newly combined analysis from two of the world's leading ...

The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure and stability of matter. Now an international collaboration of physicists ...

If dark matter is made from "dark" versions of the basic building blocks of ordinary matter, the world's largest particle accelerator should be able to pin it down, a new study suggests. When you ...

Just after the Tevatron collider at Fermilab in Illinois released its results, the Large Hadron Collider’s (LHC) ATLAS and CMS experiment teams presented their latest preliminary results in the search ...

A ghost is haunting our universe. This has been known in astronomy and cosmology for decades. Observations suggest that about 85% of all the matter in the universe is mysterious and invisible. These ...

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.

The neutrino “fog” is beginning to materialize. Lightweight subatomic particles called neutrinos have begun elbowing their way into the data of experiments not designed to spot them. Two experiments, ...

AUSTIN (KXAN) — The most sensitive dark matter detector in the world is showing results in the hunt for the hypothetical particle. The results: they can’t find it. “If you think of the search for dark ...

The LZ's central detector in a surface lab clean room before delivery and installation underground. Located deep underground, the LZ (Lux-Zeplin) detector takes elaborate precautions to screen out ...
