Gravity is by far the weakest of nature’s four fundamental forces, and physicists have spent decades asking a deceptively ...

Physicists just discovered a brand-new particle that appears to be an exotic cousin to the protons and neutrons that make up ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than ...

The LHCb collaboration at CERN has confirmed the observation of an ultra-rare particle decay that has puzzled physicists for ...

Snappily named Xi-cc-plus, Cern physicists spotted the particle in shower of debris that lit up Large Hadron Collider ...

Physicists have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

Researchers at CERN have announced a new particle that is like a slightly heavier version of the proton. This new particle, ...

CHICAGO (CBS) -- A powerful new particle accelerator that could be set up at Fermilab, a telescope to observe the oldest light in the universe, and research to learn more about mysteries such as dark ...

What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at ...

Particle physics seeks to understand the fundamental constituents of matter and the forces that govern their interactions. The field has evolved from early studies of protons, neutrons and electrons ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

In the literal sense, nothing is simpler than an elementary particle: By definition, a particle is considered to be elementary only if there is no evidence that it is made up of smaller constituents.
