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 ...

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 ...

What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at ...

The Committee on Elementary-Particle Physics was convened by the National Research Council's Board on Physics and Astronomy to assess the field of elementary-particle physics as part of the survey ...

In particle physics, data long outlives the detectors that generate it. A decade ago the 4,100-metric-ton Collider Detector at Fermilab (CDF) reached the end of its life and was shut down, stripped 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 ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than ...

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 ...

Dr. Randolf Pohl from the Institute for Physics at Johannes Gutenberg University Mainz (JGU), have successfully conducted experiments on hydrogen atoms which allow testing of the Standard Model of ...

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 ...

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 ...
