In the literal sense, nothing is simpler than an elementary particle: By definition, a particle is considered to be elementary only if there is no evidence that it is made up of smaller constituents.

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 ...

Physicists at Fermilab in Chicago have improved the measurement of a subatomic particle called the W boson. Their result won't just help physicists better understand exotic particles; it also narrows ...

In 2024, the T2K Collaboration started to collect new neutrino data following several upgrades to the experiment that included new types of detectors. One of these, called SuperFGD, has a mass of ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

Elementary particle physics reflects the human quest to understand the basic building blocks of nature and the rules that govern the physical world. This quest has led not only to critical scientific ...

Researchers at Fermilab, who run the Tevatron particle accelerator, say they’ve discovered a new particle “anomaly,” leading people to think they may have uncovered a new elementary particle or new ...

Every few years, scientists take a step back to take a broader look at their field and determine what questions are most pressing—and what tools they will need to answer those questions. This year the ...

RECENTLY J. Barnóthy 1 has proposed an explanation of the elementary particles (protons, electrons, etc.) in terms of serial universes, each enclosed in one of higher order. The elementary particles ...

Todd Pedlar has been a professor in the Physics Department since 2003. Some of his course topics include Classical Physics, Electricity and Magnetism, Quantum Mechanics, Nuclear and Particle Physics, ...
