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 ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Scientists working at the world's biggest atom smasher near Geneva have announced the discovery of a new subatomic particle that looks remarkably like the long-sought Higgs boson. Sometimes called the ...

As the name suggests, particle accelerators involve accelerating subatomic particles to incredibly high speeds and smashing ...

Scientists working in the realm of subatomic physics study particles - specifically, subatomic particles such as electrons, protons, and neutrons - and how they exist and interact. By doing so, they ...

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 ...

The isotope lead-208 was predicted to be extremely stable and perfectly spherical because of the “magic” numbers of electrons and protons orbiting its nucleus. When researchers blasted lead-208 with ...

“There’s a lot of meanings for ‘small,’” says Janet Conrad, a particle physicist at the Massachusetts Institute of Technology ...

Physicists at CERN have reported the first observations of matter-antimatter imbalance in a subatomic particle 'baryon', offering clues as to why matter dominates in the universe. Particles of ...
