The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

Doug Cowen is a professor of astronomy, astrophysics and physics at Pennsylvania State University; Derek Fox is an associate professor of astronomy and astrophysics at Pennsylvania State University; ...

As the nucleus splits, it also releases its neutrons. These neutrons bounce around at incredible speeds until some eventually ...

The isotope lead-208 was predicted to be extremely stable and perfectly spherical because of the “magic” numbers of electrons and protons orbiting its nucleus. When researchers blasted lead-208 with ...

To peer into the heart of the sun, a 13.7-meter-wide stainless steel shell lined with over 2,200 light-gathering sensors hides deep under a mountain in central Italy. Known as the Borexino experiment, ...

What would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic, but it happens to shed light on our intuitions about radiation, the ...

CERN, the world’s largest atom smasher, says it has observed three new "exotic particles" while carrying out its third run of collisions. After a three-year pause for maintenance and routine checks, ...

GENEVA — The physics lab that’s home to the world’s largest atom smasher announced on Tuesday the observation of three new “exotic particles” that could provide clues about the force that binds ...

Quantum chromodynamics, or QCD, is the theory of the strong interaction between quarks and gluons. Lattice QCD uses supercomputers to explore 'tantalizing hints' of new physics in discrepancies ...

The Nobel-Prize-winning physicist Peter Higgs has died at age 94. He was celebrated for his work on the mass of subatomic particles. Today the University of Edinburgh announced the death of the Nobel ...

The quantum world is a pretty wild one, where the seemingly impossible happens all the time: Teensy objects separated by miles are tied to one another, and particles can even be in two places at once.

In 2015, the world's most powerful atom smasher, the Large Hadron Collider, will restart. The particle accelerator has already discovered the Higgs boson, the so-called "God particle," and when it ...
