The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Deep inside every atom lies a restless world of quarks and gluons—the tiny building ...

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The ...

The strongest force in the universe is called, aptly, the strong force. We never get to witness its fearsome power because it works only across subatomic distances, where it binds quarks together ...

Scientists have used CERN's Large Hadron Collider (LHC) to uncover what they say is an entirely new type of particle, dubbed ...

For more than half a century, particle physicists have theorized the existence of a “glueball,” a particle made entirely of gluons. While the past few decades have produced some compelling candidates, ...

Particle and high energy physics seeks to understand the fundamental constituents of matter and the interactions that govern them across the smallest distance scales and highest energies. The Standard ...

Nobel Laureate Peter Higgs died earlier this year. Twelve years ago this week, physicists discovered the particle that bears his name. When researchers at the Large Hadron Collider announced the ...

Dark matter, a type of matter that does not emit, reflect or absorb light, is predicted to account for most of the matter in ...

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest building blocks in nature: atomic nuclei. In new research published in Nature ...

The Standard Model of Particle Physics accounts for four fundamental forces—strong, weak, electromagnetism, and gravity—but for decades, scientists have wondered if an elusive fifth force might be at ...
