"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

Here’s how physicists calculate g-2, the value that will determine whether the muon is giving us a sign of new physics. Like racecars on a track, thousands of particles called muons zip around an ...

The most powerful formula in physics starts with a slender S, the symbol for a sort of sum known as an integral. Further along comes a second S, representing a quantity known as action. Together, ...

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe.

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...
