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 ...

Restricting a strange class of particles known as anyons to one dimension could force them into adopting one of two new forms, models suggest, hinting at new fundamental interactions in particle ...

This open meeting of the Committee on Elementary Particle Physics will feature a panel on the benefits of elementary particle physics (EPP). The meeting will be ...

An experiment deep underground hopes to explain the gallium anomaly. The gallium anomaly dates back 20 years to a confusing experimental finding. The answer could represent a fundamental shift, or it ...

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 ...

Ten years ago, scientists announced the discovery of the Higgs boson, which helps explain why elementary particles (the smallest building blocks of nature) have mass. When you purchase through links ...

Quarks are among the smallest things that science has discovered, shown experimentally to be about a million billion times smaller than a grain of sand. Joshua Jackson, Luther College senior of East ...

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 ...

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

A committee-supported project or activity that has been completed and for which output dissemination has begun. Its committee has been disbanded and closeout procedures are underway. Elementary ...
