The Belle II experiment at the SuperKEKB accelerator measures particle interactions with extreme precision. Collisions of electron and positron beams create the high-energy environment needed to ...

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 ...

For more than a decade, physicists have argued (and counter-argued) that a subatomic particle can be separated from certain quantum properties, such as its spin—a phenomenon known as the Cheshire cat ...

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 ...

Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing investigation of CP symmetry. The anomalies could be ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

Discover the fascinating world of particle physics — the most fundamental building blocks of the universe and the forces that connect them. When you purchase through links on our site, we may earn an ...
