A SUBATOMIC particle is a particle that composes an atom. Everything in the universe is made of atoms, microscopic pieces of matter. Atoms are incredibly tiny and are difficult to see even under a ...

GENEVA – Scientists at the world’s biggest atom smasher hailed the discovery of “the missing cornerstone of physics” Wednesday, cheering the apparent end of a decades-long quest for a new subatomic ...

A report in April suggesting a giant atom smasher may have detected a never-seen-before subatomic particle had physicists at the edge of their seats with hope, albeit with a healthy dose of skepticism ...

High-speed collisions at a giant atom smasher have produced what physicists say is a new particle, a heavier relative of the familiar neutron. The particle is called the neutral Xi-sub-b. When it's ...

This lesson utilizes an adaptation of the board game Subatomic: An Atom Building Game to help students learn about the different parts that make up an atom. During their turn, players can choose to ...

WASHINGTON (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 ...

Physicists working with the LHCb experiment at CERN have proven that a subatomic particle can switch into its antiparticle and back again. The researchers were able to prove this using extremely ...

The Department of Energy’s Fermi National Accelerator Laboratory near Chicago. If accurate, it’s a sign that the theories forming the foundation of modern particle physics don’t tell the whole story.

European researchers say they have discovered a new subatomic particle that helps confirm our knowledge about how quarks bind – one of the basic forces in the shaping of matter. The European ...
