After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

Why did this particle mysteriously disintegrate?

New research from the Fermi National Accelerator Laboratory (FermiLab) in Illinois has found that a tiny subatomic particle appears to be disobeying the laws of physics, which could open up a host of ...

Observations of extremely rare subatomic particle actions have allowed scientists to put one of the most stringent limits yet on the reigning theory of particle physics. Physicists at the world's ...

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 ...

For the first time, physicists have confirmed that certain subatomic particles have mass and that they could account for a large proportion of matter in the universe, the so-called dark matter that ...

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 ...

The discovery of the Higgs boson hasn’t led to a explosion of new physics. Now, some scientists think that hidden physics may ...

In 2023, Earth was struck by a subatomic particle so energetic that, on paper, it should not exist. The neutrino, calculated ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been ...
