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 ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

A clever mathematical tool known as virtual particles unlocks the strange and mysterious inner workings of subatomic particles. What happens to these particles within atoms would stay unexplained ...

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 ...

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of ...

They're tiny, invisible, and travel across the universe. And trillions of them just flew through your body. What are they? Neutrinos ‒ and scientists Wednesday announced the discovery of the most ...

China is nearing completion of an advanced facility to measure neutrinos, the smallest subatomic particles known to physicists. Its underground central sphere will soon be sealed off and filled with ...

Neutrinos are very small, neutral subatomic particles that rarely interact with ordinary matter and are thus sometimes ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

Neutrinos have been with us since the beginning. They existed alongside prehistoric humans, dinosaurs and the first scattered crumbs of life on Earth. The birth of the solar system, the formation of ...

WASHINGTON, Aug 10 (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their ...
