Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same ...

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 ...

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 ...

Why did this particle mysteriously disintegrate?

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 ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe ...

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 ...

What is meant, when an experiment anticipates less than a quarter of an event, and four are registered by the detector? That number discrepancy lies at the heart of a new conundrum of kaons: ...
