Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining signatures of string theory.

The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

Visualization of the allowed values of "dial settings" in the scattering amplitudes that describe the probability for particles to interact in the models introduced in this new work. The regions in ...

If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by subatomic particles like protons and the quarks and gluons that make them up.

Scientists working at CERN’s Large Hadron Collider may be seeing the strongest hints yet of physics beyond the Standard Model — the decades-old theory that explains the fundamental particles and ...

Because someone said that the Large Hardon Collider is cooler than the Burj Dubai, I ended up spending an hour reading about hadrons, mesons, baryons, and the such. I swear I felt more than a couple ...
